Out of curiosity, I went to familysearch.org, the LDS database, and searched for those names. I found an (Al) Ella Maby in Florida, NY, born 1872, with more data, showed up there in 1892 census. I believe Al was a nickname for Ella which was in those days a common name for girls.
I assumed the Delaware was not the state, but a husband's surname. There were many Delawares in that area at that time. I found nothing else on that name later. No marriage; no death record; no kids.
In 1880 census she was shown as a boarder with a family of a different name.
Without more information, it is not possible to know if it's the same person or not.
In those days, it was not uncommon for people to use different names than their documents showed, if they had any.
