I do have your Great-Grandfather, b. Oct 26 1875 in Donoff, Russia, d. Jan 22, 1939 in Montana, he married Dec 27, 1897 in Dietel, (Oleschna), Russia to Sophia Weinmeister, b April 24 1875 in Dietel, Russia, died June 13 1967 in Dietel, Russia. They had 7 children, 6 girls and 1 son.
Some informarion I have on them so far in their notes
David Hettinger 37, wife Sophie 37, children; Sophie 4, Jacob 3, and Maria Katharina 16. Immigrated to the United States from Bremen, Germany, on Oct 10, 1912, and arriving Baltimore, Maryland aboard the "SS Main" in Oct ?. 1912. They were going on to David's brother Jacob Hettinger in Park City, Montana.
1920 US Federal Census: Household members, Dave Hettinger 44, wife Sofie 44, children: Sofie 13, Marie 6, Lydia 4 and 8 mos., and Elisabeth 3 and 2 mos. They were living in Laurel, Yellowstone, Montana. The family owns their home free of mortgage, at 419 Durland Ave. Dave works as a beet laborer. The couple and daughter Sofie are Russian born and entered the US in 1913 .
I have his ancestry back to Michael Hettinger b. 1716 in Germany d. 1775 in Donhof, Russia.
I became related to the Hettinger line when my grandfather George Bangert (1877-1917) married in 1907 a second time to Amelia "Mollie" Hettinger (1885-1970).
Hope this helps, and if you want more infromation let me know. If you want to go back from your great-gandfather, I can send you a descendant chart on what I have so-far. Betty Carvalho, California firstname.lastname@example.org
