My source is from Royal Spear and he has Juliana as the first child of this couple. she married Jacob Teskey ye younger in 1746 she died in 1783. I do not have anything else on them or their children. If I come across it I will let you know. Judy I have all the children of Johann and Katherine if any would like to know them.. I will be putting it all down on the switzer page once I get to them. My connection to the Switzer's is from the 4th generation down. When they married into the Shier line. Hope this helps. Judy
