The Kapp's traditionally were foresters/woodcutters - hence Kapp. Try and send more info, like more information on the 10 kids, names, dates so I can try to find a match. My g.grandmother was one of 11 children and sometimes when one sibling dies young, the others only recall those still living in their time. There are a lot of Ernst Philippus Kapp's as its a family name passed to every generation where possible. Traditionally its Ernst, not Ernest, but both work. A rough time frame or estimate dates of birth/death would also help. I can find no Sophia right now, but I have quite a few Ernst's with no spouses to date. More details would help.
