I found you on The Edmund Price and Jane Webb Facebook Group ,that is likely your best resource for Price connections. I didn`t check Keirstead/ Kierstead Facebook Group to see if you are there but also helpful mostly Obituaries but they are helpful in that they add each persons line.
You likely have or can access these attachments but will send along anyway. The headstone picture took myself last summer, likely on find a Grave anyway. Also a map from Provincial archives showing all the Keirsteads who lived on the Forks Stream road and the former N Clark place where the Forks Stream Brook meets the Canaan River was my father`s farm, my nephew now owns it.
You likely have more of family tree information than I do but if you would like some of my close more recent family ,let me know.
You can find me on facebook as CONNIE BLACK RYDER.
PS : Also George Black and Amelia Jane Keirstead my G Grand mother and G Grandfather,already posted on Price Facebook Group .
