From online research, hopefully correct - corrections requested:
Maude Nettie Caswell (1866-1948) was born in 1867 in Maine, perhaps in Union, the daughter of Lendall Caswell and his wife Ellen (Gower) Caswell.
In 1892, Maude married George D. Rowe (1866-1934), the son of Charles S. Rowe and his wife Huldah (Stearns) Rowe, both of whom were born in Smithfield, Maine.
George D. Rowe was a physician in Augusta, Maine. He was associated with the Maine State Asylum, now known as Riverview Psychiatric Center. I found George and Maude living in Providence, Rhode Island in the 1910-1930 Censuses. No one else was listed as living with them. I haven't yet found them in the 1900 Census, so am not sure if they ever had any children.
If you have any corrections and/or information to share on any of the people mentioned above, please leave a comment for the benefit of other researchers.
