I do not have a death record for John Crowley. I have been trying to find him for some time now. All the docuements I have on him are up until 1894/95. After that I cannot find anything on him.
In John Anthony Hamilton's name change record where I found a lot of this information it says that Mary's son John entered into theWellseley school system as John Hamilton. Maybe her son atteneded a private school away from home because Wellseley is in Massachusetts and accorded to the name change document, William and Mary were married in NY ~1898. I originally thought that maybe John was still living with his biological father in Massachusetts in 1900. However, if John, entered into the school system as John HAMILTON, chances are he was not living with his biological father. The record also stated that Mary and John CROWLEY were divorced and not widowed so I have no idea when John CROWLEY died.
