I have little doubt that everyone of the name Luzader, Lewsader, Lewzader, etc. are related. From the WPA index for Vigo Co. Indiana Marriages, I have a marriage date of Nov. 22, 1916, for John LEWZADER and Malvina Morris. Malvina d. 1966, in Terre Haute, Indiana. Would this John be one and the same as your Henry? I don't have John in my genealogy program yet. The spelling of LEWZADER seems to have been adopted exclusivley by the descendants of Abel LEWZADER, son of Andrew LUZADER, b. 1791. Janet Fuls is a direct descendant of Abel. I'm sure she and her mother can help you with information on this line. There is a lot of help in the Forum, if you could post some of your information, we can probably fill in the blanks.
