Benjamin Jolly (Bef. 1760-Aft 1731)
http://wc.rootsweb.ancestry.com/cgi-bin/igm.cgi?op=DESC&...
had a son Colwell P Jolly who married Mary Thrift, daughter of William. Their son, Archibald T Jolly (~1803-1864), married Elizabeth Perkins (d bef 1850). I don't know the relationship between Elizabeth Perkins and Hughty, I would guess his daughter. She was likely born soon after 1803 based on her husband's age.

Benjamin Jolly (Bef. 1760-Aft 1731) left a will which gives items in his Will to:
"my grandson Benjamin M. (note: son of Daniel)
"my son Daniel"
"my grandchild Susanna Spain"
"my son Colwell"
"Colwell's two sons Archibald C. and Benjamin M.
"my grandson Benjamin Jolly, son of Colwell
"Lucy Ann Jolly daughter of Benjamin M. Jolly"
"balance of my estate to my two sons Daniel Jolly and Colwell Jolly"
Executors: Benjamin M. Jolly and my friend Henry Young
Dated: February 24, 1831
Witnessed by:
James G. Young, Hughty Perkins, and Robert G. Young

So it still seems as if Lucy Thrift who married Hughty Perkins was probably a close relative (daughter or possibly a niece?) of William Thrift of Dinwiddie Co. William & Martha were having kids up to ~1798. Mary Thrift was born about 10 years before THIS Lucy, and also married 10 or more years before this Lucy. Lucy could have been Mary's younger sister, IF there is no conflict with the apparent union between Lucy Ann Thrift & unknown Adams. Could Adams have been her first husband who died early?
