Since Family Tree DNA is having a sale right now, I've decided to take full advantage (this will be my Christmas present). One thing I'm doing is retesting both my maternal and paternal lines. The first time I went through Ancestry. I've determined that the analysis was probably correct but the interpretation for the haplogroups is definitely suspect (have a few earlier posts about this). One question I have is I'm doing the full sequence on my mtDNA.
I'm also planning to have a "new" cousin tested, if she is willing. Per information handed down from my grandmother, my cousin's great grandmother was my grandmother's half sister. Based on information gathered so far, I think that the connection is via my great-grandmother (grandmom's mom) but I've never been able to fully connect them via paper trail and am hoping that this will possibly provide the link. My question is would I need to also do the full sequence on my cousin if I'm doing the full sequence?
