I am a daughter in-law to John David Allwin (9-12-1903/8-29-1960 in Laurel, MT. The families name originally only had one L in it - Alwin or Alvin. On the tombstone, it was written Alvin. We understand that in German, the v was pronounced w. My father-in-laws father was David Allwin married to Christine Hoff. They migrated from Germany to Russia and then back to Germany and to the U. S. We do not know anything about the family other than that. David is burried in Wimbleton, SD. John David ended up in North Dakota where his mother re-married. John had one sister, Lydia Brietzke from Minot, ND. We are looking for siblings, or cousins. Our family tree is a little short. John David, came to North Dakota as a very young man and worked there where he met my mother-in-law, Amanda Duda. They later came to Montana. We believe that so me David's family went to California but they were never heard from after that. There was question as to whether they may have died in the fire there in San Fancisco.
