Jason Lincoln Chase is my maternal great grandfather (Chase-4539). Is my y-DNA test able to tell me anything? If not, what test would, if any. The links are me(male), my mom, her mom, Chase-4539(male).
Also, https://www.wikitree.com/wiki/Stevens-11258 has done family finder and so have I but (Chase 4539) does not mention me, only Holly. I am confused. HALP!!! What, if anything, should I be doing. I know already (Stevens-11258) is a (NEW!) cousin for me.
