Common maternal ancestor but different haplogroups

My MtDNA test result reports me as being haplogroup A with 8 HVR1 differences (from RSRS). I have 'No [HVR1] matches found at this level of testing' for (1) matches heading (2) ancestral origins heading (3) haplogroup origins heading.

A researcher has identified a possible maternal ancestor (call her Sara) and a 7 people (call them 1-7) who have proven maternal links to Sara. The researcher has pointed out that my haplogroup A differs from the haplogroup K reported by 1-7 and queried this with me.

Which is more likely? My haplogroup result is wrong and I am actually K not A? The researcher is wrong: I do not share Sara as a common ancestor with 1-7? Both my haplogroup A and my maternal link to Sara are correct; in other words is it possible for descendants from a common maternal line (i.e. my great great ... grandmother Sarah to belong to different haplogroups (A and K in this case)?

By "maternal" do you mean matrilineal or not?

Sara can not be the matrilineal ancestor of both you and the other group of people. She can be the matrilineal ancestor of either you or them, or neither, but not both.

Some more data which I'd appreciate input on. My sequence is identical to theirs (the group of 7) with the following exception: my first sequence result is T16093Y whereas the group of 7 are either T16093Y or T16093C. Is it possible to share the sequence bar this one exception, yet not share the haplogroup?

My sequence (A haplogroup)
T16093Y, A16129G, T16187C, C16189T, T16223C, T16224C, G16230A, T16278C

Their sequence (K or K1a-T195C! haplogroup)
T16093C or T16093Y, A16129G, T16187C, C16189T, T16223C, T16224C, G16230A, T16278C
C146T, C152T, A247G, C497T, 522.1A, 522.2C, 315.1C, 522.3A, 522.4C

I got that totally wrong then. I'm glad it has been resolved.
