Send a message to the person who requested a photo of the grave monument of Mary Ann Flintoff with the following comment:
Possible ancestor through Mary Ann's husband, William. I'd ask for the details about possible cousins/share my own details with those who request, but I'm not yet certain that this is the correct William Flintoff from my family. I'm still working to confirm that he is one of my greatx3 uncles, and being able to see the gravestone details may help when I discuss this with older relatives who visited the gravesite as children. Thank you for your hard work!
