Update: thank you for help so far, it appears that Rose was not Druyahn, but Rose Klein, daughter of Aaron Klein and Celia.

And as requested, here are snapshots of some censuses, I've attached snips from 1900, 1905 and 1925 showing their 4 children Celia, David, Clara and Samuel.

Herman arrived in New York in 1889 according to these documents, and was naturalised in 1899/1900 in NYC.

Does this help at all?
Very many thanks
Emma Cole
