From the 1900 Cleveland Directory: at 338 Lincoln av. there was Henry Oehling, stonectr. Henry F. Oehling, coremkr Henry M. Oehling, foreman and William Oehling, bricklayer (There was also a Valentine Oehling, res. at 21 Wagner.)
One of these Henrys married my great-grandfather's sister, Ida Mae Meredith (nee Barner), the widow of Alfred E. Meredith, sometime after 1891.
There's also a Henry Oehling listed in online directory for the Cuyahoga Co. Ohio Probation Court and Naturalization Records 1859-1901. Arrival from Germany 5/1865, Declaration 12/15/1874, and Naturalization 10/4/1880.
Not directly researching the Oehling family, but thought that this might be another branch that people might be interested in.Wouldn't mind getting more info about any of these fellows either, though.
