I am looking for information on a Captain Costello (perhaps, Will Costello?) who married Martha Vaughn in Escambia County, Florida sometime around 1840-45. They had a son, Will, who worked for the L&N Railroad out of Pensacola during WWI and WWII. Martha had another marriage (don't know if it was before or after) to a CREEN, also in the Escambia County area. Thanks for any info you may have.
