In answer to your querie, I will pass on what I have, although we haven't pursued this line any further...
Johnathon Finsthwait Sr., m: Sarah Clark, Johnathon Finsthwait Jr. m: Martha Hilford, Mariah Finsthwait m::Peter Harrington; Martha Harrington m: Hiram Riggs, their daughter Annie m: Davis.

Thomas Hilford m:Elizabeth Owens, children: David; Robert; Patience m:Robert Owens; Boaz; Martha m: Johnathon Finsthwait; Elizabeth and Mary.

Notes: Source for Thomas Hilford His Will of 1784, naming heirs as his wife Elizabeth (Owens). Also named his children David, Robert, Zadoc, Boaz, Martha, Elizabeth and Mary.

Patience Hilford: Probate records Vol 38 P 161-162, 29 June 1804 with William, Samuel, Nancy Downs (wife of Benjamain) and Elizabeth as heirs.
Sarah Owens to Zadock Hilford 25 Mar, 1796--Wm, Sam, John Owens, Nancy Downs...also mentions heirs of Eliz Hilford (Eliz Dorman, David, Boz, Robert & Martha Hilford wife of Johnathon Finsthwait. (my notes read "here till proven further") I have lots of Killen's but haven't connected this Martha with them. If I go back and take another look and find something along that lines I will sure let you know.
