Getting others to Test
I have been trying to get others to test. It seems the Prouse family are a suspicious lot and are either not interested or are concerned about their privacy being violated. But I will continue to search!
I have some information I would like to share with you privately at this stage to get your opinion on what I am seeing.
I have located a couple of people whose Y-DNA very closely match mine, but have a different surname. We suspect that there may have been a Prowse/Prouse parent since there is a brick wall and stories that the parents may have died and left the child with others to raise. If it was an illegitimate birth and the child took the name of the people he was living with might account for the name being different.
I have two individuals, one took a Y-37 test and we have a 35/37 match and another who took a Y-67 test and we have a 64/67 match including all of the Nulls.
Their surnames are different, but could they be the distant cousins you mentioned?
I have two or three others that have the same criteria.
If my research holds up I believe I know who the MRCA is. I hope I can locate the Prouse/Prowse who is willing to be tested and link him to the ones i have spoken of.
i appreciate you help and input, Ann!

[QUOTE=RLProuse;432174]
These are my nulls: DYS458, DYS455, DYS454, DYS449, DYS576, DYS570, S31, DYS590, DYS425, DYS450, DYS481, DYS520, DYS568, DYS487
I see you followed through on my suggestion at WikiTree to post a query here. As I responded there, autosomal no-calls are a different matter.
However, I did locate an old map of positions of Y-STRs along the Y chromosome. It doesn't include all the markers you listed, but the ones it covers are all located in the same vicinity.
Thus this is most likely to be a deletion. It would be interesting if you could track down the most distant Y-line cousin you can find and see if he also has the deletion.

My Y-67 DNA Test had 14 Nulls
I understand the frustration of those with multiple Nulls or Deletions! My test came back with 14. I had my two sons tested and their results came back exactly like mine with the same nulls in the same locations. I questioned the results, but the helpdesk were sure of their findings. Since my sons were tested at different times and our results are identical random error doesn't seem likely. It is what it is.
These are my nulls: DYS458, DYS455, DYS454, DYS449, DYS576, DYS570, S31, DYS590, DYS425, DYS450, DYS481, DYS520, DYS568, DYS487
Have any of you taken the time to see what your autosomal raw data can tell you. Yes, it is a huge file, but I believe I have found some interesting things you might want to check out for yourself.
Nulls may not be as rare as you think. In my case I had 14 nulls in my Y67 test results. So..I downloaded my Ancestry Raw Data and using Excel, sorted on one of the last two columns which contain the T, C, G, or A symbols. Be sure to sort A to Z so the zeros or -- appear at the top. If there are any nulls they will show up as zeros in Ancestry results and two hyphens (--) in FF in place of the letters. Be sure to highlight all fields before sorting so all the data remains in context. If you have any questions about sorting or anything else, don't hesitate to email me!
Next, delete all rsults below the zeros or --. We are only interested in the Nulls. The null problem may turn out to be helpful! Be sure to keep a copy of your results with all the raw data. It is all valuable!
I recently made contact with an 11th Cousin twice removed. We exchanged raw data and discovered we had a large number of matching nulls. Our paper trail also proves that we have many common ancestors.
We were surprised to learn that I had 12,193 nulls out of 701,479 and he had 9,119 of 680,545. Another correspondent had 11,720 nulls out of 693,734 alleles tested. These nulls represent about 1% of our tested genes. I took the Y-67 test, the other two individuals Y-37, thus the lower number of nulls & the total tested.
I don't know if there is a Null Project already established, but I am interested in getting one going if there is interest.
Those of us with multiple nulls are frustrated because we only get 12 results and rarely 25, 37 and 67 and 111 are astronomically rare!!! I have found thirteen or fourteen people with multiple nulls ranging from 5 to 14 in the Y37 or Y67 tests. I found 5 more between Y67 and Y100.
I believe that sharing Nulls with others would open a new way of researching and discovering our roots. Since there is no DNA recorded, sharing the raw data will not compromise or privacy.
If you have a working relationship with Excel this project is for you. If you are a novice, we will help you!
I am just beginning my research and would appreciate anyone interested and willing to share only the nulls of your results to contact me.
Up to now nulls have been an artifact of genetics and little understood and a hinderance to our research. I believe they have a roll to play in our quest for ways to learn more about our ancestors and actually help us identify others we might be related.
Goal: Create a database of Null results.
Are you willing to share only your nulls and by working together, see if our problem could actually be beneficial. These files are quite large. Mine was 701,479 rows on the excel spreadsheet.

And the Turner Adm is wonderful -- she helped me break through a brick wall in the Turner line.

He has 4 null values.
I wish FTDNA would mark these with 00 or something else that would be easy to search for. Maybe Darren will send this in as a suggestion.

thanks
Thanks everyone. my first step will be to contact family tree to have them take a second look at my results. Lets hope they're wrong and I can get a full panel of results to look at

Originally posted by rt-sails View PostI support Ann's advice; report it and ask for a review. It's worth being sure. If those three markers really are nulls (deletions) that's rare. In my project, with >600 Y-STR results, we've seen only a few nulls (spread out among the 600 men) and some of those went away after review.
With any null value, the apparent genetic distance is so large that the only ones you can match with FTDNA's algorithm will have nulls on the same markers.How is genetic distance calculated for NULL values?
For Y-Chromosome DNA STR matching, genetic distance is calculated as a single NULL causing event. The NULL value causing event is treated as a single step event with a genetic distance of one. The one exception is for the STR marker DYS439. The difference there between a value of say 12 and a NULL value is calculated as a genetic distance of 12.

This looks to me like a lab reporting problem and your results were pushed as completed and shouldn't have been. To have 3 null voids in one panel (markers 13-25) sends up a red flag.

Good luck!

So it appears that at some point in your patrilineage, a small segment of the Y chromosome was deleted. This is not all that uncommon--almost the entire haplogroup N has such a deletion.
However, these three null values will prevent you from matching anyone according to FTDNA's automatic algorithm. To find matches, you would have to use Ysearch instead, where a zero means simply that the marker should be ignored for matching purposes.Last edited by lgmayka; 20 March 2015, 05:52 AM.
