What I found, so far, is that blacks with the surname of Perpena, and its various spellings, are endemic to FL until after 1870. Between 1840 and 1860 blacks by this surname were living in Key West. In 1830 there 2 women by this surname in St. Johns county. In 1870 there was an "explosion" or people with this surname in Key West, St Augustine, and Fernandina. In addition to 1 man who was born in FL but moved to VA. I'm related to the Fernandina Perpena's. Is there way to link and/or eliminate the others? I've been looking at Civil War documents and census information, but I can't find any information that links my great great great grandfather to the Key West or St. Augustine Perpena's. What should I do next?
