Hello again! I later-after I sent you the first message - found an 1850 census record for John - still no wife - I think she must have died when the last baby was born, maybe, since he was only 7 months old in this census from Charleston, SC. John 53 Germany Merchant Elizabeth 21 John 19 Clerk Georgiana 17 Leopold 16 Jane 14 Theodore 12 Caroline 10 Gustavis 8 Herman 4 Michael 7/12 Also in Charleston, I located Harmon(Herman?) Klinck 36 Germany Clerk in a grocery(no family), and Henry Klinck 19 Germany Clerk in a grocery.Maybe they worked in John's grocery since he was a merchant!Maybe they are his brother and a nephew?
John Klinck was located in city directories beginning in 1825 an 1828 so the naturalization in 1824 so it makes sense that he would start showing up then.Good luck with your hunt!Glad I could offer some help!Jan
