You may already have it, but you can see the full death certificate on www.familysearch.org, including full DOB and Date of death, as well as cemetery name.

Margaret/Marguerite and William Donnelly are also names from my family, but I don't know of a connection. The age is right for my William to be a brother of your Marguerite.

My William (great-grandfather) arrived in NYC about 1880, moved to NJ about 1891 and lived until 1931.

Good luck!
Margaret Donnelly
