My grgr-grandmother MaryAnn Croke and husband Thomas Laffan were first shown in Wisconsin in the 1850 Fed Census. She was born c1828 and he c1820. They were living in Scott Twp, Columbia Co w/children James b.1847 and Mary b.1849 or 50. They moved to Newport Twp still in Columbia Co and had 5 more children Joanna, Anna, William, John, and Thomas.

I'd appreciate hearing from anyone who could help me to connect this couple to other siblings or parents.
