About William Roysden
As you know, there were lots of variations to this surname but I think almost all were of the same related families.
We start with Ann Goad born ca 1738 in Virginia who married a Risden, William reportedly. The Goads, Lawsons, Phillips et al went from Grayson/Montgomery counties,Virginiato Anderson County, Tenn ca 1804.
In 1830 Anderson, we find Robert Risenden enumerate on the census.He was age 60/70, hence born in the 1770s. William and Ann had a son Robert who went to Knox County, Tenn. in 1795. This must be he.
In1830 Campbell County, Tenn. was an Isaac Riseden, age 30/40 with a wife 20/30 and sons under 5 and 5/10. He lived near Goads, Lawsons,Phillips, Smiddys, Elwicks, all related.
In a 1823 in Campbell, there had been an Abraham Risedon.
Ann (Goad) Risden/Roysden had brothers named Abraham and Robert.
By 1840, Isaac had disappeared from the census but there was a Nancy Risden , age 30/40 with three sons, one each under 5, 5/10,10/15.This matches the family of Isaac in 1830 with some of the ame neighbors, Richardsons, Sharps, Harmons, Ridenours. Two Goads,Joshua, nephew of Ann (Goad_ Risden and Aaron, Joshua's son, were on this census.
Ny 1850, most were in Scott County formed in 1849.
I believe any of the Risden family, however spelled, who have roots in these counties are likely descendants of Ann (Goad) Risden. That includes those from Jamestown, Tenn.
Ann reportedly had anorher son Jesse who webt to Anderson and then Missouri and a son Nathan who went to Indiana ca 1820
Little of this is proved but with an uncommon name such as this, the evidence mounts.
