(But first: HAPPY BIRTHDAY MOM :))
Went to the "members only" page of the DAR website and logged in.
Found some new cousins/fellow members of DAR/descendants of Philip Proctor.
Traced one line, saw that they started in New York state and ended in Utah.
So yeah, they were Mormons.
Googled the family name and found an autobiography of a cousin that someone had put online... he was a polygamist in Utah.
One of his wives had "Pratt" as her maiden name.
As in, Parley P. Pratt... was her dad.
I'm related to Parley P. Pratt by marriage.
