Ida is not included in the list of siblings - either living or deceased - on Saul's Death Notice. If she lived long enough to get married - which seems to be implied by name Ida (Gottesman) Weiss - then she should have been.
She is not on the 1900 Census with her parents and siblings, nor the 1905 NY Census with her parents etc., nor any other Census I have seen with her parents.
Judith Berlowitz - do you happen to recall what Documentation you saw that led you to add her? Are you quite sure she belongs in this family, and if so, why?
