Mary Ann Otis - born 1834 - location unknown. Married Thomas Peckham in Oswego, NY.

1880 Census states her father was born in Ireland and her mother was born in England.

My grandmother left a lot of handwritten info on family tree and had this to say about the Otis line...
Siblings:
Caroline Otis Coad
Medora Otis Smith (or Sarah Otis Smith)
Henry Otis
John Otis
George Otis

Any help - especially who Mary Ann's parents were is appreciated!
