I would like more information on the family of William Irwin, and Louisa J. Carpenter. They lived in Derry, Westmoreland Co., PA. William b. 1827 Louisa b. Lancaster Co., PA 1832, d. April 1872. Children: Anna M, Albert, William Henry, Elizabeth, Mary Ella, Charles. Louisa's mother, Margaret Carpenter, d. April 1872. May 1872, Louisa delivered twin sons. One survived. Second twin son d. August 1872.
In his will, William Irwin talks about "the time of our great family tragedy." Are there any descendants who would have more information on this family. Louisa was my g.g.grandfather's sister. Thanks,Don Carpenter
