Hendrick D. Vroom was the half-brother of my ancestor Jannetje Vroom. I have seen no documentation of his birth, or if his middle name was Dumont, as was his brother's (Pieter Dumont Vroom). If the Bible has his birth date and/or his full name, could you let me know what it says? It sounds like the Bible information begins about that time, but if it includes information from his parent' generation, it would be interesting to have that as well.
This is an interesting family group. Hendrick and Pieter were staunch patriots during the Revolution. When their father died, they and their stepmother and half sister apparently moved to Jamaica on Long Island, where the stepmother had relatives, and there she married her 3rd husband, a Loyalist. Hendrick and Pieter ended up back in New Jersey, probably to an inheritance of land, and Jannetje married and went to Nova Scotia with other Loyalist immigrants. Thanks for your help!
