The dates of your Samuel E. ROOD and mine are the same so I expect we are talking about the same person.In his will, Samuel names Sheldon SQUIRE as his father-in-law.Plus, in the photo album (ca 1900) we have from his daughter Florence there are numerous pictures of people with the surname of SQUIRE but none with the surname of DONAHUE.(about half the photos have no surnames)
It was based on that information that I figured Hannah's surname was SQUIRE not DONAHUE.However, it occurs to me that Sheldon SQUIRE may not have been her father, rather perhaps he was her stepfather.I'm fairly certain Hannah did not remarry after Simon died as she appears with the name ROOD in all the censuses from 1865 till her death in 1906 and she is burried under the name of Hannah ROOD.
AS for the children, the ones I know of are Eugene S. ROOD b. ca 1853 d. after 1893 Florence E. b 1854 d. 1918 Sarah E. b ca 1858 Charles b ca 1859
All of these children lived with their mother HANNAH in Bristol, Ontario Co. NY.
