I can do lookups for most Massachusetts towns bef 1850, thought the records of Boston city proper are lacking in this collection, and are often earlier on in the 1700s for the most part.
If i go to the library, then I can do lookups on the NEHGS (New England Historic and Genealogical Society), which includes records up to 1910, plus some birth and marriage to 1915, plus alot of other databases that i've yet to tap into. I usually go once or twice a week to my local branch.
I can access Ancestry Library edition as well, though the search feature doesnt seem to be as effective on this version, so the more info you give me the better.
Also, HeritageQuest online, for census and Persi and such. The census on this site usually indexes the heads only, though Ancestry Library helps pick up the slack.
Also through BPL online, i can access some historic newpapers and obits. i think mostly late 1800s-1900s, though I'de have to look up which it is. I believe the NY Times in there as well.
I own the book The Old Families of Salisbury and Amesbury. A very big book with good genealogies. not always completely accurate for some families, once theyve left the area, but still a good place to start. this is a few volumes plus corrections, bound into one big book.
I also can access alot of books from the book delivery at BPL in Boston, as well as obits and such on microfilm. These i can't do as often, as I don't always have the train fare to get there (disabled, little income lol).
I'm in the Revere/Lynn/Everett area, so when it's nice out, I can usually get to the cemetery for photos and such (i'm a FindAGrave volunteer as well)
