Re: Seeking John Mangin/Mangan and Polly Richardson descendants

I am also interested in this family. Snow and Zebediah Richardson and Robert Huston Jr were witnesses to Stephen Julien's will in 1829.I am sure there is a connection from my family to this family.My line is Mary Ann Julien daughter of Elihu Julien (brother of Stephen) married Elijah Stewart.Elijah Stewart is buried in Wright Cemetery in Shelby with the Juliens and is buried next to Moses Stewart who I believe is his brother.Moses Stewart was married to Sarah Richardson.Azariah Julien married Cynthia Richardson.The Juliens, McClures and Stewart all came from Newberry Co South Carolina when the Quakers made a mass exodus in late 1790s even though most had already left the church.There are also Richardson's there but from anything I have read Zebediah was from Pa but I am not sure.
I also have that a Catherine Savage married a Daniel Stewart in 1833
