I also have a Kling/Cling family in Lancaster Co., PA. The father was Adam (Adam may be a middle name; if so his first name has 6 letters [the tombstone is unreadable]), wife Mary (?) and his 4 girls were born between 1808 and 1818 in Lancaster Co. His sister (Margaret Ann, married to Frederick Miller) also lived in Lancaster Co. but emigrated somewhat later, about 1821. By 1830 Adam had moved west to Ohio and eventually Indiana. In later censuses he reported his birthplace as Württemburg.
I'm searching for any relatives and immigration information.
