I have a genealogical mystery that needs solving, and could use some new ideas to help me out. During my genealogy research I ran across someone who had an old family Bible with some marriages and deaths recorded. One of the deaths was for a gentleman by the name of Sigmund Friedenberg (sometimes spelled "Freidenberg"), and the DOD was provided as December 28, 1928. I know he was living in Richmond County (Staten Island), New York, when the 1910 and 1920 federal census was taken, and assume he was still there when he died. However, a paid records search of the NYC Municipal Archives turned up nothing on his death for the 1928-1929 time period (and the search was conducted for all the boroughs, including Manhattan, Brooklyn, Staten Island, Queens, and Bronx). Is it possible he died at a Staten Island residence, but never showed up in the NYC death records? In addition, his obituary was not carried in the NY Times at any point during the December 29, 1928 - January 1, 1929 period. Considering the amount of effort that used to go into journaling proper death, marriage and birth dates in old family Bibles, do you still think the death date for Sigmund might have been incorrect? It would seem strange since all of the other deaths listed were exactly correct! I've searched and searched the records on ancestry.com and familysearch.org and have come up empty-handed on any verification of Sigmund's death. I have solved many genealogical mysteries during my research--some of them quite difficult, indeed--but this one has me completely perplexed. Any ideas that might help me solve this mystery would be greatly appreciated. Thanks.
