Hi, Ted. If Morris was born in Russia and died in the U.S., there should be immigration and census records on file. Ancestry.com and FamilySearch can help you locate these records.
Immigration form will have:
- His approximate age, profession, and the town or region where he was born and/or lived before emigrating
- Contact info for next of kin
- Any family members he emigrated with
- Contact info for any family or friends he has in the U.S.
- His destination in the U.S.
Census form will have:
- His approximate age, country of birth (as it was called in that year: "Empire of Russia", "Poland", etc.), profession
- Family members in the same household
- Place of residence
- Military service, ability to read and write, income, etc.
Naturalization form may have:
- Birth date
- Birth place
- Name variation, for example, if he emigrated under the name Moshe Zilberman
- Spouse's name
- When and where they married
- How many children they have, their names and birthdates
Since you know Morris and Toby's children's names, the easiest way to locate this family is first to search for their U.S. census records. [1900 or 1910 census, Father: Morris Silverman; Mother: Toby; Children: Joseph, Sarah, Ida, Edward etc. Be prepared for spelling variations and nicknames!] Then search for matching immigration and naturalization records. Once you have those details, you can use a database such as JewishGen's All Poland Database [https://www.jewishgen.org/databases/] to locate the related family in the related region in Eastern Europe.
I hope this is useful!
