I would try the Queens Archives to see if your Amanda was born in Pearsalls, or the area.Eardeley states that they were all in Blue Point by 1890.Unknown when they moved there.Benjamin and Mary Hendrickson were married in Hempstead, and may have stayed there for awhile? According to Eardeley, this Benjamin was not on the 1850 Hempstead Census. To add to the confusion, there was a Benjamin, age 23, born New York and Mary, age 20, born New Jersey listed on the 1850 Brookhaven Census, with a 2-year old daughter, Mary.Eardeley does not seem to think this is the same Benjamin and Mary. (But he wasn't always right) Also in 1850 Brookhaven, five familys down, was an Edward Abrams, age 30 with wife Eliza Combes, age 35 along with four children. Since your main problem is establishing her parentage, you must find her death certificate, or even her marriage certificate - which may list her parents. I have to look up my New York State records, but I think that her death certificate would be at the Suffolk County Archives and/or New York State Archives. I am not an Abrams - I am married to one.We are both from Lynbrook, but no longer live in New York.I would have to look in the records to see how you and he are related.He is the great-great-grandson of Valentine Abrams, son of Edward and Charity (Pearsall) Abrams.I have helped Clay Abrams transcribe the Eardeley Notes because I love genealogy.
