Researching online, I found an Alice Sidney Wilder who married Charles Henry Morse. Charles has a New Hampshire connection. However, the lady in the photograph may be a completely different Alice Wilder Morse. Perhaps Morse is her maiden, rather than married name. Hopefully a reader will step forward to clear up the mystery.
Assuming the lady is Alice Sidney (Wilder) Morse, here is what I found:
Alice Sidney Wilder was born 30 August 1858 in Hingham, Massachusetts, the daughter of William Crocker Wilder, born in 1829, and his wife Eliza M. (Bates) Crocker, born in 1833, both born in Hingham, Massachusetts. Alice's paternal grandparents were Crocker and Mary Ann (Spooner) Wilder. Her maternal grandparents were Eliel and Hannah (Stoddard) Bates.
On 1 January 1884, Alice married Charles Henry Morse, who was born 16 April 1860 in Derry, New Hampshire, the son of Joshua and Basmath Ann (Alexander) Morse, both of Derry, New Hampshire. His paternal grandparents were Robert and Alice (Dodge) Morse. I haven't yet found out the parents of Basmath Ann Alexander.
Charles Henry and Alice Sidney (Wilder) Morse had at least one child, a son William Wilder Morse. Alice Sidney (Wilder) Morse died in 1895. In 1910, Charles Henry Morse married Kate Belle Barnard and had, I believe, 4 more children.
If you have any corrections, additions or insights regarding the information presented above, especially if you think the lady in the photograph is not the Alice Wilder Morse I've outlined, please make a comment in the comments box or contact me directly. One thing that concerns me is that the lady in the photograph seems a bit old to have been born in 1858, but the photograph has not been stored well over the years and is very faded, perhaps not a good candidate for reliable dating.
Thanks for stopping by!
