Caleb Foster (1786-about 1873) is believed to have been born in Maryland, and
migrated to Lower St. Clair around 1811 where he married Polly "Mary" Snodgrass (1783-1854), daughter of Robert Snodgrass and Jean White. Robert, a native of Lancaster County, was an early settler of Allegheny County, having purchased his land from the Penn family in 1794. This land, located in what is now the Banksville area, was inherited by Robert's children after his death. In 1835, Caleb sold digging rights for coal on this land. Caleb was a successful farmer and a member of MLUP Church, where he became an elder in 1854.
Caleb and Polly had seven children including Robert Snodgrass (1819-1864), Ross (1819-1864), Addison (1822-1869) and Jane (1813-1899). Addison, a local constable, married Isabel (1834-1911-see obituary below) and had at least six children (including Emma, who died at age 23, and Willie, died age 3). Caleb's daughter, Harriett, married James Milholland. When Harriett was left a widow with young children, her unmarried sister, Jane, stepped in to help raise the children until Harriett married Richard Knowlson, a native of England.
Caleb's second wife, whom he married shortly after Polly died, was named Maria.
