I was very excited when my parents agreed to test. I thought when the tests came through I'd be able to sort my matches into paternal or maternal.
But no. Seems I am a closer predicted relation to a whole heap of matches than either parent. Father matches one segment. Mother matches a different segment. I match a smaller portion of each segment but added together it makes a bigger overall match.
Oh well. I'll take a fresh look tomorrow to see if I can sort it out.

Due to the World War II, in 1960s in Europe, there were a couple of documented cases of siblings getting married, as they had been separated by war being very young. And without biological parents around they could not establish their true identity. In one case I recall, they had visited his ancestral home around twenty years after the war, and she realized that she was there before and the girl their (his & her) family thought it was her killed in the bombardment must have been some other girl...

I think I was just tired.
I've spent a lot of time on my own results, and I wanted to know where I had got it right.
At least I understand now why I was so confused. I'd picked up that some matches seemed to match both sides, but I thought that was an error in my reasoning. It wasn't.
Limerick and Tipperary, that's what it is. Both maternal and paternal sides have one branch from each. Actually, so do both my husband's parents.
I'm sorting out the segments very well now. Making great progress.

Noticed this discussion and it reminded me of a paper I stumbled on recently. Sounds like there is scattered earlier evidence of endogamy, and it must have been common when hunter gatherers were in small bands (although they probably also captured women from other groups or acquired mates during times when different groups gathered for some big party.)

Abstract
The transition from mobile to sedentary life was one of the greatest social challenges of the human past. Yet little is known about the impact of this fundamental change on social interactions amongst early Neolithic communities, which are best recorded in the Near East. The importance of social processes associated with these economic and ecological changes has long been underestimated. However, ethnographic observations demonstrate that generalized reciprocity - such as open access to resources and land - had to be reduced to a circumscribed group before regular farming and herding could be successfully established. Our aim was thus to investigate the role of familial relationships as one possible factor within this process of segregation as recorded directly in the skeletal remains, rather than based on hypothetical correlations such as house types and social units. Here we present the revealing results of the systematically recorded epigenetic characteristics of teeth and skulls of the late Pre-Pottery Neolithic community of Basta in Southern Jordan (Figure S1). Additionally, mobility was reconstructed via a systematic strontium (Sr) isotope analysis of tooth enamel of the Basta individuals. The frequency of congenitally missing maxillary lateral incisors in the 9,000-year-old community of Basta is exceptionally high (35.7%). Genetic studies and a worldwide comparison of the general rate of this dental anomaly in modern and historic populations show that the enhanced frequency can only be explained by close familial relationships akin to endogamy. This is supported by strontium isotope analyses of teeth, indicating a local origin of almost all investigated individuals. Yet, the accompanying archaeological finds document far-reaching economic exchange with neighboring groups and a population density hitherto unparalleled. We thus conclude that endogamy in the early Neolithic village of Basta was not due to geographic isolation or a lack of exogamous mating partners but a socio-cultural choice.

Viking Genes includes four studies: Viking III, Viking II, Viking Health Study - Shetland (VIKING) and Orkney Complex Disease Study (ORCADES). They involve over 8,000 volunteers who agreed to take part. We soon hope to recruit 2,000 more, bringing the total number of participants up to 10,000.

I've never tried to download raw data for calculating and such like. But and however, I recently settled on a particular maternal line as being valid since I have a match with tree at Ancestry. This is my Green maternal line (paternal within a maternal branch). One guy along the way, if I remember right, has a maternal grandmother who is also his first cousin once removed. I hope I figured that out right. This was way back in colonial Maryland. Apparently that family was very finicky about marrying outside of their social group (relatives and immediate descendants of the founding Calverts).Last edited by PDHOTLEN; 10 January 2015, 12:17 PM.

Originally posted by PDHOTLEN View PostYeah, I'm off somewhat. It looks more like first cousin twice removed(?). Greens marrying Greens. One of those Green lines goes back to the Netherlands. I still haven't added the second colonial governor of Maryland to my current official tree. He was in office only a short time before he died of some fever.
I downloaded felix's latest modal and my wife and I are fifth cousins which is within reason.
