I am a great grandson of BenZion and a grandson of Adolph.
Regarding Albert: Until just recently, I was unable to garner any additional information on Albert other than the census info cited in your posting. About two months ago, I found a wrongful death lawsuit, filed on behalf of the deceased Ben Zion, which listed surviving immediate family members as co-plaintiffs. Albert was listed and shown to be a resident of Philadelphia at the time. If memory serves me correctly, this was around 1920. Should a more accurate time frame be needed, please contact me.
Of course, I have information on Adolph, as well as some on Arthur, the youngest child, including pictures.
