I've had a similar problem with certain family members not having enough records to trace back through them. You may be able to trace down to your line though. I haven't yet researched my cousin lineages on the Slayton side, but I do know that some of my family moved to Texas and Louisiana sometime within the last 4 generations. I have posted My direct paternal lineage in response to another poster's question. You might try tracing down their children's lines to see if you find anything that sounds familiar to you from your family. I'll post back here if I come across anything myself. I'm focusing on parts of my mother's line at the moment. So, it may be a month or 2 before I get back on the Slayton Branch.
