John:Apologies for the slow response.I have no further information on Lucy Creath.She was not mentioned in her father's, Robert, will in 1851 so I assume she had died before then. Robert's will mentions some grandchildren (children of son Wm. and dau. Polly Grimes). I have a birthdate,Jan 31, 1816 in Ripley Co., IN with a twin Margaret, which came from their grandfather's Rev War file at the DAR in Wash. DC. with a BIG ?.This info was noted as being from a family Bible but not further sourced in the DAR file.I wish I could be of more help.
