Forgive a question from a 'not quite a novice anymore' lister, but your answers may help others wanting to enlarge their testing results, but not knowing the best way to proceed. We start from an adoption in my husband's paternal line. So 1/4 of my children's ancestry is a mystery. Skipping over the obvious step of yDNA testing her father for now....my daughter took the FTDNA Family Finder test. She's found 53 matches so far, but we have not found her paternal ancestry.. Then 23&me offered a one-day sale on its Complete Edition that includes Relative Finder. I took that. I've got 477 matches so far which I am only beginning to explore. Now we think we will be able to persuade her father to be tested. We want to get both the fullest yDNA test available and a cousinsage finder test. The 67 marker yDNA test + the FF test from FTDNA is about the same price as a Complete Edition from 23&Me, so price is not an issue. I cannot figure out how many yDNA markers 23&Me tests, if they test markers at all. (As a female, I did not get any yDNA data from my Complete Edition test). I cannot figure out if FTDNA and 23andme raw data for Y can be compared. From earlier postings on this list, it looks like FF and RF test different snps, so are complementary, and not comparable. Whichever company we choose for the cousinage test, will the data we already have from the other company be useless? How can I maximize the usefulness of the testing we have already done in choosing this next set of tests? Thanks, Rebecca
