All, Maybe you can help me solve a problem. I believe that my 6th great-grandfather is JONATHAN HOUSTON born about 1700-1704 and son to Anthony Houston who immigrated with Jonathan to New Castle on the Delaware about 1707-1711 upon the death of William Houston, brother to Anthony who was already in New Castle. I believe that James Houston who died shortly before November 14, 1760 (date of probate) in Kent County, Delaware may be a son of Jonathan Houston. The problem is that James's probate is signed by a "John Houstown" (James also spelled his last name Houstown) instead of a Jonathan Houston. So the question is, was it common to use both John and Jonathan interchangeably and could John and Jonathan Houston be one in the same? If they were not used interchangeably was it possible that a Jonathan would become known as a John as he matured? Jim Houston Fort Worth, Texas
