Before I begin my search of my unknown family, I think I've summed it up to this: "Some people have secrets they aren't free to share because of hurtful memories are hard for them to bear & repair so we need to show them how much we care." I may not find much information but it's worth a try.
So far I have and found:
Husband: Cooper Levy (Kopel) born on Dec. 4,1882 from Craiova,Roumania. Death: in 1950 (Parkinsons Disease) I have 1910 census ~ Kopel age 26, Anna age 23,Harry age 12 brooklyn NY, WW1 Registration card, 1930 census~ Cooper age 45,Anna age 41, Harry age 20,William age 18,Adolph age 15,Sylvia age 10, and WW2 Registration card,with 2 addresses on it.
From the census their language from what I can see is Yeddish~ Hebrew with Germanic language? They were Naturalized 1900- 1901. I will be sending out for their marriage document soon.Maybe it will have their parents names on it? Married January 16,1909 in Manhattan,NY.
children: Harry, William, Adolph,Sylvia.
Wife: Anna Germain (German) ~ Bulgaria

I can not find the 1920 census, and not sure how hard it will be to find them when they came over.

The marriage should have the name of the parents. My grandparents were married in Manhattan in 1905. Theirs had the parents names.

Opps... duplicate!

My great-grandfather Antonino Leone was married twice in Manhattan, once in 1907 and once in 1920.

Here is a scan of the 1907 Marriage act:

Antonino Leone to Concetta Arena 1907 Manhattan

Here is a scan of the 1920 Marriage act:

Antonino Leone to Giuseppa Marciano 1920 Manhattan

Just you can see what to expect!

Thanks James for showing me your documents.
