Thanks so much for your input! I have a copy of EH Silliman's Death Cert.. and it lists the Del Walt Hotel as his residence for "2 years 1 month" before his death. Your additional info helped me confirm the actual address (now a boarded up old building in what looks to be a blighted commercial area in Brownsville... courtesy of Google Earth) I'm trying to account for his whereabouts between the 1930 census showing him living in Jamestown, NY with his son... and 1940-42 in Brownsville where he eventually died. Can't figure out from the DC who might have been the informant on the cert... and who made sure his body got back to Ashtabula, OH where many family members lived.
... more digging to do,I guess!! Thanks again, Sedate
