Kathy,
I'm doing a lot of work on the Homrighausen family in the US also. I've had problems with this branch as well. I've got them pretty well branched out, but I have the same roadblock with John and Magdalalene. I've got a couple of church records where they attended at the same time as my gr x 4 grandfather in the 1840s in New Philadelphia, Ohio. They only lived there a couple of years before moving west. Magdalena is buried northwest of Chicago. I've got her cemetery pic, but interestingly, she's recorded in two different cemeteries. I'd love to share info, but it seems like we're both stuck at the same point.
