Am also researching the LUZAR name, also know of others. My maiden name was LUZER but in other documents it has been found to be spelled 3 different ways. Have only gotten as far back as my GF Frank who was born in Chgo, IL around 1880 but have just recently sent for some information that may find my GGF who was named Frank and his wife who was named Mary (Marie). Family is originally from Aust/Boh as far as the census. Frank Luzer married a Mary (Marie) Svec. Will be looking forward to any response you might give.
