John Cochan (b 1780) and wife Margaret (maiden name may be Wallace) immigrated in 1811 from Ballymoney, County Antrim to Westmoreland Co., PA. He supposedly had a single brother who stayed in Antrim. They were Presbyterian. Were there many Presbyterian parishes in Ballymoney in the late 1700s and early 1800s? JoAnn Cupp Grass Valley, CA
