Thanks for your reply.The only reason I thought there might be a connection was that Edgecombe County is not too far away from Jones County, NC and this Francis I found out today was b.1798 in Va and married Feb 15, 1824 in Trenton, N. C.
I have been clicking today on the Duval site spelled with only one 'l' and found something interesting.
If you go there and check post #355 there is a link to a site that has a lot on Duval families and seems well researched with births, deaths and marriage dates.I even found the Jones County Francis Duval and wife Nancy (she was Nancy Ann Bryan) and their children and who most of them married.
I didn't find anyone named Hollan/Holland Duval or anyone married to an Askew though. Did find a few Duvals around Tarboro.That is close to Edgecomb though I think.
