She may have been b. in Germany as I haven't found much on Glance but did find Glantz. I haven't seen anything anywhere about a James marr. a Catherine Glance, but there are a lot of sites out there with information. I've seen someone else's research saying Catherine was b. 1748. There certainly were cases of lots of people marrying relatives & I'm sure the Lusk's were no exception. There seems to be speculation that Catherine was the dau. of Charles Frederick Glance of Germany. I found someone with your date of 1794, but they still had her as marrying Joseph. Could be there were 2 Catherine's. According to the info I found, Catherine b. 1794 had 5 sisters & 2 brothers. Where were this James & Catherine living?
