I suspect you're looking for Doctor John WRIGHT Belt. My grandmother had a geneological study done to support her claim to the DAR and turned up John WRIGHT Belt who is a descendant of Humphrey Belt. Let me know if you're still looking for more information. I just started putting the tree onto Ancestry.com and will be happy to scan in the document I have and send it to you.
