I am researching my husbands family.I have Cristian Ackerman b. 1821 m. Elizabeth ? b. 1826 I have one daughter listed as Margaret Ackerman b. July 4, 1869.She married Emil Clair and they had 12 children.I have them listed as in Pittsburgh, PA and know that the family was from Alsace-Lorraine originally. Cristian and Elizabeth were listed in Allegheny City, PA when they died.I know that Sharpsburg is part of Pittsburgh so feel that I am onto the right family.
