Don't forget to always misspell family names when doing your search.
Lasaine, Lazine, Lessene, Lasane, lesane, Lasainne, l'Saine, Lazaine, etc...
I think I have found at least 30% of my relatives with misspelled surnames. My LaSaines hail from South Carolina and were probably slaves of a Lessane/Lasaine family in SC. Still trying to trace.
