This may be a possibility: I have been researching Gardner Wilcox (Jr. and Sr.) for a long time. I would like you to take a look at my notes at Rootsweb, rather than putting all my information here. Focus on the 1820 and 1822 censuses: Gardner Wilcox and his wife Abigail Eccleston had two girls under the age of 5. I believe Abigail Wilcox Johnson is one and I think Nancy Wilcox could be Abigail's sister. When Abigail Wilcox married Jonathan Johnson in Plainfield, CT, the record said she was "of Voluntown". Her mother, who first married Gardner Wilcox, married second Richard Robbins (Robinson in the 1850 census and Abigail is living with them). Abigail lived in Voluntown and lived in Coventry, RI and West Greenwich, RI.
