Any insight into the parent identified in Geni has SB(W)'s parents. There are notes identified in her main profile page which state that she is the Daughter of Nathaniel and Sarah. I have these as Nathieniel Warren & Sarah Walker, but it doesn't line up with geni. Mother, name unknown is 1gen after mayflower. Notes from main page below, please contribute as I am 8th GG son.

Matthew - Wow! What a mess.
I searched for Nathaniel to see if there was a profile for Sarah in the correct place. Nathaniel's gender had been changed to "unknow", his name was basically invisible with *no data* selected from resolve conflicts (Interestingly enough, one of the other possibilities to select, already merged in as the same as him -- minnie mouse. I kid you not!), and lastly, he was married to a John Walker. Poor Nathaniel!
I'm going to at least see if I can restore your path and then I'll bring in some of the curators who focus on the Mayflower passengers to make sure the family unit is correct.
This might explain things a bit :-)
