Hello Lynda Lawson,
Thank you for posting your request on History Hub!
We suggest that you contact the New York State Department of Health, the New York City Department of Health, and the New York City Department of Records and Information Services
to request searches for marriage and death certificates. You may wish to note any name variants or broaden your search for the surrounding years. In addition, the FamilySearch Research wiki for [How to Find United States Vital Records] may be helpful.
In addition, you may also find NARA’s Resources for Genealogists, as well as the History Hub Blog titled Suggestions and Advice for Family History Researchers useful.
We hope this is helpful. Best of luck with your research!
