Thanks for the info. Yes, he's the ancestor I'm trying to search. I'd obtained the info you sent. He was born in Ohio, moved to Fort Madison, IA, then to Dunn Co, WI and is buried there. His first wife was Amanda, and his second wife Phoebe came with a family. That caused an estrangement with his son Jesse that lasted until J's death and is the reason we never knew anything about A.H. Jesse's wife was Mary Ann Moser.
Phoebe's descendant family has gotten in touch and supplied the info about Thomas & Sarah from the marriage cert for A.H. & Phoebe Sibley and that's where it stops. I think I've possibly found Thomas as a kid in the Washington Co. OH census, but am not sure about it.
