I am looking for information on Helena - perhaps a marriage record or something that might include her maiden name. Pierce is her married last name.
She was born sometime between 1801 and 1809 (every census seems to have a different year) in New York. The 1850 census implies her husband is Benjamin Pierce (born ~1770 died before 1860). She had at least two children Charles Sylvester Pierce (1841-1906) and Filena Pierce Perry (1840-1928). Helena lived with Charles's family for many years, and she died in 1878 in Florence, Kansas where Filena was living at the time. Filena buried her mother, and she shares a headstone with Filena's daughter Mabel Amelia Perry.
I am looking for information regarding Horace Hudson Pierce, born in Vermont(?) about 1836. Lived in Cook County, Illinois, New Trier Township according to 1860 Census. Had two children, Mary Ann and Jane. Wife Mary died when Jane was born in 1863.
