The Christy Family in America by Eleanor Christy Kramer and Margaret Christy Ackerman
FIRST GENERATION ANDREW
The pioneer of the Christy family in America. Born in the north of Ireland about 1700, in or near County Louth (lieth) as Lurgan Green was their Market place. He came to America from the County of Ulster, Londonderry, Ireland, in the year 1762 and landed at Philadelphia, Pennsylvania.
He brought with him his children James, John, and Ann.
It is believed that his wife died previous to his coming to the United States as there is no record of her landing. Her name was either Mary or Margaret Wilson.
The original home of the family was in Scotland, their residence in Ireland probably dating back only to the colonizing scheme of King James in 1608-1610. There are papers in which the name of John Christie of the Parish of Jaeburg appears, which seems to indicate the original home and the old way of spelling the name.
In America he lived for a few years in Mifflin County, Pennsylvania. They he moved to Salem Cross Roads., Westmoreland County, Pennsylvania. where he lived until his death. The two sons each purchased a farm there abut sold later and went further west.
He is probably buried at the Concord Cemetery where a number of his descendants are interred. (Possibly some dates might be obtained from the monuments there.)
He was a Presbyterian in faith as were his children. (It was thought that he belonged to the Seceders, a group of people who resented both the Roman Catholic Church and the Established Church of England, while he was in the old country.)
