Richard Dillon [b 1745 VA – d 1833 MS]; married Anne Lawrence [bc 1762 NC – d c 1839 MS]. He served in the American Revolution. Richard "saw service as an enlistee on the vessel 'Greyhound,' a privateersman commanded by Samuel Butler. With the capture of that vessel, he was made a prisoner on the English frigate 'Baloosa' which carried 36 guns and was commanded by a Captain Kennedy, a Scotsman. After a nine-month imprisonment, he again returned to Bertie County." About 1810 he moved to Pike County, MS., , 
I found Richard in the federal census at Ancestry.com. The 1820 US Census shows Richard Dillon in Pike Co., MS.
Free white males: 1 45+ over
Free white females: 1 45+ over; 1 26 – 44; 1 under 10 years old.
Slaves: 13. Total: 17 people
I’m confident that this is my ancestor because on the same page were Laurence, Clarkson & Willis Dillon. Those were the names of three of the sons of Richard & Anne.
I was unsuccessful at finding Richard Dillon in the 1830 US Census but when I searched further I found Dillons in the Mississippi state census reports for 1841 & 1845. I found all four sons of Richard & Anne Dillon: Lawrence, Clarkston, Theophilus & Willis, in both years.
