I can help you make some connections to the Picketts and Boulwares.
Musco Boulware and Nancy Pickett (d/o Thomas Pickett of Caroline Co, VA) (who moved to SC from VA after the Revolutionary War and settled in Fairfield Co.)had three daughters marry Picketts. Elizabeth and Sarah Pickett married John B. Pickett in Fairfield Co.
Their daughter Nancy Boulware married Jeptha Pickett (my ggggrandfather and ggggrandmother). Their son Jeptha Boulware Pickett (my gggrandfather) married Nancy Elizabeth Raines (d/o William Green Raines and Catherine Boulware (d/o Musco Boulware and Nancy Pickett)
Is this confusing enough for you? If you would like to contact me at email@example.com I will be happy to give you everything I have.
