Ruth, I have a bit on their oldest, son Thomas from the PA Biographical Record:


The following is copied from the "Biographical Record, Washington County, Pennsylvania, published 1893".

"John Cain was a native of Ireland, and in eariy manhood immigrated to America, locating in Maryland, where he was united in marriage with Mary Means about 1783.

About 1785 he came to Green County PA, where the brothers of his wife had located a year or two before.

He died about 1830 and his wife returned to Maryland after his death to live with her relatives.

The following children were born to them:
Sons:
Thomas (b. 1784, m. 1812 Mary Montague, b. 1784 - d. 1860),

Dennis (m. Airy Gordon, daughter of John Adam and Cassandra Holland Gordon b. July 1, 1796 - d. Jun 10, 1884),


Thomas Cain, the eldest son in the above mentioned family, was born in 1784, in Maryland, and when a young child, was brought by his parents to Green County. Almost every farmer operated a distillery in those days, and the youth of Thomas was passed in assisting in that work, and in the duties of the farm. He was naturally an apt and intelligent boy and his meager educational opportunities were thus supplemented. He was also a mechanical genius, and made good use of almost any tool."
