There is a school registration for a David Schulman bn c1882 father Benjamin in Manchester
I was looking at Benjamin for his father earlier...
Scotland Census, 1891
Benjamin Shulman.
Born 1862.
St George
Midlothian. Same area as David
I think his wife is Dina Shulman. Maybe siblings of David, Samuel Shulman, 1885,
Dora Shulman, 1890.
The 1891, 1901 and Davids death all fit.
