I am seeking info on 2 brothers, John and Henry Voelker or it could have been "Voelkers" orginally. Both arrived on Ellis Island in 1860's. Henry stayed in New york for a while but later moved to Philadelphia and by 1893 had a Son, Harry Voelker, no "s'. Henry was married to Bertha Mary Mitilda Michaels. John stayed in New York and changed his last name to "Felker". The two brothers never saw each other again. Does anyone have information on this connection?
