I am seeking information on Otto J. Lotz born Dec 16 1888 in Waldenburg, Schlesien, Germany), his wife Anna Haning (b. 1892 in Gratflug, Germany) and their 2 daughters Bertha (b. abt 1910 in either MN or Germany) and Marion Lotz (b. abt 1931 in Ithaca). There were also 2 sons Frederick Joseph and Herbert Otto - I have quite a bit of info on the sons, but not the daughters and no one seems to know what happened to the parents.
The last I find a reference to Otto (alive) is on the 1930 census in Buffalo, Erie County, NY.
I found Anna (Widowed) working as a servant on Merchant St in Interlaken on the 1940 census, Marion is boarding in someone's home also in Interlaken. I also found Anna listed on the Ithaca City Directory 1946, 1949 and 1951 with Herbert and//or Marion. Then on the 1952 City Directory, Marion is listed a studen but appears to be living alone in Ithaca. I know she was still alive in the early-mid 7o's somewhere in NY (her nephew was living in Maryland and they went up to visit her a couple times).
Otto must've died sometime between 1930-1940 and I suspect in Buffalo. Also this is likely where Marion was born.
If anyone can help that would be great.
