The 1880 census for Smyrna, Kent Co DE has Leonard Revis b 1852 in England, living as a boarder in home of a Mary Primrose. Ther is a later record I have seen online which has his marriage. The William Revis b 1885 in DE should be documented in his Social Security application, most likely Leonard's' son. I believe Leonard may be related to Frederick Revis b in England ca 1845 who emigrated to Brooklyn with a large family in early 1870's. Either way, there is no connection to the Reavis/Revis family descended from Edward Reavis of VA.
