I am looking for information on William Henry Addison b. 1822, d. before 1853.He was the son of George Cook Addison and Susannah Hervey who were married in 1821 in Balto County.George Cook Addison was the son of Isaac Simmonds Addison (1797-1858) and Sarah Murray who were married 1811 in Baltimore County. Isaac Simmonds Addison s/o George Mitchell Addison (1764- ?) married abt. 1785 to Ann Simmonds
George Mitchell Addison s/o Robert Addison (1743-1785) born in Scotland married abt. 1753 to Isabella Cook who died in 1809.
I think we are talking about the same family. Would be interested in sharing information.
