Although I have yet to find more on the elusive Englishman who came to New Brunswick, married Mary Goodwin, and produced 4 children with her in Fredericton (John Goodwin Hawksley, Mary Hawksley, Sarah Brown Hawksley, and Margaret Elizabeth Hawksley), I DO have a letter from England regarding the surname.
As a volunteer for NEHGS, my name goes in their annual report. This person saw my name and wrote to inquire after a family connection. Even though I can only tell her what little I know (that the Hawksley ancestor did come from England to New Brunswick, and his first son was born in Fredericton in 1810), it does feel nice to have received the letter. You never know when a person may turn out to be a very good new friend.
I have been focused very much on the Hawksley side lately. I've tried to glean clues from naming patterns (Isabel is EVERYWHERE, and I think that Mary Goodwin's mother - a "Workman" - is either an Isabel, Elizabeth, or Sarah Workman; likewise, I believe her father is a James Goodwin).
I've tried to glean information from Loyalist sites, but there is nothing that pertains to this family (Mr. Goodwin was a Loyalist from NJ or NY, and settled in St. John, New Brunswick; he was a POW at one point, but escaped).
Last, but not least, I've tried to find information on British soldiers of the Revolution and War of 1812. Thus far, I can't find online muster rolls. I expect this will require a trip to Fredericton, which I am simply not prepared to make this year. (My husband will be in Korea; my son is 5, and I just can't imagine him sitting quietly as I search records and cemeteries.)
Alas, our move to Alaska will take us farther away from New Brunswick. However, I will do my best to keep researching via the net and regular mail, until I have exhausted my options!
