Hi, Read your post and could not find any of these children. You might want to check out the Medina County Ohio Census for 1840 and 1850 and you will find out what happened to Joseph Salisbury and his wife Maria Bogardus Salisbury. I could not find the children you mentioned but there is quite a list of their children in the census for that county.
Maybe your Joseph Salisbury is a different one, I do not know, at least rootweb and the other do not show one. My GGG Grandmother Melissa Catherine Salisbury Haynes is shown in a picture that I have, standing in front of her daughter's house in Holgate, Henry County, Ohio. My GG Grandmother was Adaline Haynes Osborn and she is standing there with my GG grandfather and Grandfather.
I was born in the little town of Holgate 70 years ago.
