The Kilmon Family of Westmoreland County, Virginia

I am looking especially for links from the Kilmon Family of Westmoreland County, Virginia to possible connection to Accomack County, VA (the Eastern Shore) and nearby Maryland area. Spellings may include Killmon, Killman, Kilman, Kelmon.

Patriarch in Westmoreland thus far is Ira Kilmon: sons of Ira are Ira, Samuel, Washington, and Ellis: Daughters are Effie and Ruth.

One perplexment, an "orphaned" reference to the marriage of an Elizabeth Kilmon/Kelmon of Westmoreland County in 1829.

Elsewise, no one else in Westmoreland County is "findable" in any "published" sources.

My father is Samuel Kilmon, Jr. son of the son Samuel, above, grandson of Patriarch Ira of Cherry Orchard Point in Westmoreland County. Other Kilmon "centers" are the "Red Chin" area of Westmoreland County, near Montross, and Coles Point, across the Lower Machodoc Creek from Cherry Orchard.

Any ideas would be appreciated.
