I have been researching the Lusk family for my brother-in-law. I use Ancestry.com and found a William Lusk who married Charity Runyan on 25 December 1806 in Tazewell County, Virginia.
Ancestry.com. Virginia Marriages, 1740-1850 [database on-line]. Provo, UT, USA: The Generations Network, Inc., 1999. Original data: Dodd, Jordan R., et al.. Early American Marriages: Virginia to 1850. Bountiful, UT, USA: Precision Indexing Publishers.
They are buried in the Lusk Cemetery, Auglaize County, Ohio.
Others have added photos of their headstones on Ancestry.com.
