Jane: John O'Brien and Cleopha Regensburger had a daughter named Eileen Ann O'Brien. I am the first cousin once removed of Eileen's husband David Paul Wetzel. Somewhere I have the address where the Regensburger lived in Evanston....I believe it was either Clarion Ave. or Idlewild Ave. I always been somewhat interested in the Regensburgers from Oldenburg because the paternal side of my family (RUDOLPH, VOLZ, HOELKER, VOGELSANG) hails from Oldenburg also. In fact, I have a grand aunt that in a nun in the Sisters of St. Francis Convent there. I have not found a direct connection between any of these names and Regensburger. Another interesting fact though.....my gr grandfather (STEIGERWALD) either sold or bought that house in the Evanston area. I'm continually amazed the smallness of the world. Roy
