Evan - sorry to be so tardy about this. My spare time and with it my genealogy is sorely lacking these days.
I'm sorry I do not have a specific website outlining my Perrin genealogy. There are lots of sources most of them undocumented out there and I have to admit some of my lineage taken from them. I inherited a "blueprint" of my branch of the Perrin family done sometime I believe in the 30's and Stanley Perin's book with its appendix on the Perrin family of Rehoboth, Massachusetts forms much of what I have.
If you have anyone specifically in mind, I'd be happy to share what I have.
