Henry Smerdon appears on deeds for Richmond Co., GA 1798 & 1799.The deeds relate to William Morgan who owned lots in Augusta and had dealings with merchants in London, England. He may be the same Henry Smerdon who was in Charleston, SC listed as broker, vendue master, auctioneer/commercial merchant and marine insurance broker 1802-9.
One Antersia C. Smerdon m. Henry Morris in Charleston, SC.She was d/o Elias Smerdon of Charleston, SC.Maybe this is another connection to Henry.
Another document that places Henry Smerdon in Richmond Co., GA area comes from SC Mag. of Anc. Research Vol. XVII:
Campbellton, 5/4/1791....we certify that we saw Mr. Barkly Martin set up a list of inhabitants of Edgefield Co., SC at Hammonds Warehouse this day....Henry Smerdon & Wm. Covington.
I am not a Smerdon researcher.I hope this is helpful to you in your search.
