A friend of mine is a great-granddaughter of Elizabeth Windisch, b. 31 Aug 1849 in NY. She marr. Anto Guenther on 25 Apr 1872 in Buffalo. Her confirmation certificate shows her father as Johann (possibly middle name) Windisch & mother as Margaretha. She was confirmed in 1863 in Buffalo. I can't find Elizabeth with her parents in the 1850, 1860 or 1870 Buffalo census. Maybe she went by another name. Conrad's dau. Catherin was born abt 1849, but you have her married to someone else. Any suggestions?
