I need some guidance on where to look and what kind of records to look for. I am doing research in St. Louis, MO on a WINGLER family and have found where a few went over into Ill. I found a marriage on one of the sons in St. Clair Co., on the Ill marriage index site. It was a Nicholas Wingler married Catharine Kolkmann 30 Oct 1883. I have no idea now where to look for any more information on them or their family or descendants. I would appreciate any advice. Thanks so much ahead of time. Beckye
