Penelope Clark married first Reuben Rowland and 2nd Jonathan Landers. From the second marriage, one of the sons was named Rowland Landers, which more or less indicates that Reuben and Jonathan were friends before his death.
Have been unable to find a will or anything that would give a list of the
children of Penelope Clark and Reuben Rowland but do know they had a son,
Reuben who married a Patsey Anna Ewing and moved to South Carolina.
