I have finally traced the Berwick lineage and hope that this info might help others. My Grandfather was Gordon Wilmer Berwick. His father was Clarence Homer Berwick. Clarence Homer Berwick's father was Ueo Isaac Sweetser and his mother was Minnie Bell Berwick (Although the daughters took the last name Sweetser, for some reason my great-grandfather and his brother (Andrew) who died of typhoid, took the surname Berwick.) Minnie Bell's father and mother were Zadock Pierce Berwick (b. 1844 in Stanstead, PQ) and Lois Climenia Mosher. Zadock (Zed)'s father was Charles George Berwick who was born in 1821 England. It appears he may have come with his father, Edward Cooper Berwick (b. 1802). I can't be certain, but Edward Cooper's father may have been Denis Berwick's father (Denis listed as b. 1784). This is speculation on my part until I have paper proof.
Zadock and Lois' children were: Jessica Louisa Berwick (b. 1868); Minnie Bell Berwick (b. 1870); John E. (b. 1872); C.P. Berwick; Frank Berwick; Harley Berwick; and Ethel Berwick. Zadock and Lois are buried together at the Lakeview Cemetary in Westmore, VT.
Charles George Berwick and Louisa's children were: Eliza (1842); Zadock Pierce (1844); Mary (1847); Henry (1849); Norman Samuel; Cinderella; Rosena (1853); Herbert (1859); William (1865); Winnona May (1872); Gertrude (1876); Addison (1881) and, Willard Leslie. I do have a copy of Zadock's death certificate that lists Charles as his father.
Edward Cooper Berwick and Elizabeth's children were: William T.; Enoch; George (1822 England); and Charles George.
Denis Berwick's children are listed as Daniel (1826 England); Henry(1835 England); and Ellen. His wife was listed as Mary.
I really hope this info is able to help people who have been searching in these lines.
