Searching for Robert Anderson of Lancaster county, PA,, born about 1756. His son Irwin's biography says that Robert Anderson was "a soldier of the Revolution, descended from a pioneer family of Lancaster county, whither they had emigrated from Ireland prior to the Revolution". PA Archives indicate there were 5 Robert Andersons who served in Lancaster militias: 1 from Colerain twp, 1 from East Strasburg twp, 1 from Elizabeth twp, and 2 from Leacock twp (Sr. and Jr.). I have tentatively eliminated all but the one from Elizabeth and "Jr." from Leacock. The latter remains a mystery because Robert Anderson Sr's only son named Robert was born in 1776, way too young to have served in the Revolution. My Robert Anderson is not registered with DAR, and he apparently is not one of the Donegal Andersons as they are fairly well documented. He moved west after the war and settled in Allegheny county. Any clues leading to Robert Anderson's origins greatly appreciated.
