I can help with your second query, someone else will have to do the first one. My records show that Catherine Elizabeth was the daughter of John Caspar b. c. 1660. She and Johann Christopher were married in southwell Estastes. I have no record of Sebastian having a daugher Katherine. Sebastian was the father of the famous Barbara who married Paul Heck. She and Paul are buried about 15 minutes from where I live. I have pictures of that on my website. www.geocities.com/judydrysdale/Heck.html and on www.geocities.com/keepsakebook under misc. pictures. I hope that helps. Judy from Ontario.
