I was informed of a Match between two Peter Crandalls with the same birth date and different parents: Crandall-87 amd Crandall-296. The wife of one of them has two Peter Crandall husbands, adding another Peter Crandall, Crandall-906. Doing a little research turned up little that I have access to, going back to John "Elder" Crandall, or Crandall-3. There is a nice essay by a biographer about how confused this line is.
The link I found that could be helpful has some sources:
http://freepages.genealogy.rootsweb.ancestry.com/~nanc/crandall/aqwg01.htm#2509C
but I don't know if this is a reputable source, and again, the lines are unclear.
Thanks for any thoughts/opinions/facts.
