These Patterson family groups are of English origin, I believe. There are no Scots names among the known related groups, in any case. These are Protestant families, often Baptist in southern MO, Presbyterian both earlier and later. I haven't found any connection to the Pattersons in early PA or other Irish lines. I'm looking in NC and VA for Matthew's grandparents and parents. I have retained information only on Pattersons in VA, NC, TN, MO. Other (all!) Pattersons in early MO interest me and I'm entering them in my data to try to sort out who belongs to which early land record, so if your Pattersons were in MO 1790-1830 I'd especially like to hear from you.
