You can try the Enoch Pratt Free Library's Main branch on Cathedral St. in downtown Baltimore. It has varies times to include Saturdays, Sundays and evenings. I have found much information that includes: all baltimore city directories, ships passenger lists, grave yard burial lists, all the federal census's, church records and all the newspapers that had been in Baltimore ( The Sun, News American...). Parking is tight so take change for meters or pay for parking in the parking gargage near by. Good Luck. Slainte, Maria Rooney
