I have several maternal ancestors who arrived on this continent prior to the American Revolution.
[I indicate my web-based sources for the information below, though for most I am relying on the poorly cited research of others.]
1) The Betts and the Stoughtons
My eighth great grandparents, Richard Betts and Joanna Chamberlain were married in Ipswich, Massachusetts Bay Colony - in 1648. It is thought Joanna arrived by 1635, and Richard mid-1640s. [source source]. Joanna Chamberlain was the daughter of Elizabeth Stoughton and Richard Chamberlain, and the granddaughter of Rev Thomas and Katherine Stoughton.
2) Hortons and Langtons
9th great grandparents, Barnabas Horton and Mary Langton are said to have immigrated c. 1630 on the ship "Swallow." [source] - Living in Massachusetts and Connecticut prior to settling in Southold, Long Island.
Barnabas Horton's son, Caleb, married Abigail Hallock. Abigail's father, William Hallock, likely arrived in Southold, Long Island ca. 1640. [source]
4) Van Everys
Brothers Myndert and Carsten Frederickse (sons of Frederick Van Iveren) likely immigrated to New Amsterdam in the 1640s or 1650s, with Myndert marrying Catharina Burger (Burghart) in New Amsterdam in 1656. [source]. Most of the descendants of Myndert and Carsten took the surname of either Van Every or Van Avery. Myndert was my 8th great grandfather.
5) Swayzes and Kinges
John Sweezey [Swayze], another eighth great grandfather, immigrated prior to 1650. [source]. He married Catherine Kinge in 1650 in Salem, Essex, Massachusetts. He settled in Suffolk, Long Island.
Catherine emigrated with her father, William, prior to 1635
They settled at Salem, Massachusetts. He was admitted a freeman there May 25, 1636. He had grants of land of forty acres on Jeffrey's Creek, now Manchester-by-the-Sea; thirty acres at Royal-side at the head of Bass river, now Beverly, and he located his homestead there. He was a grand juror in 1637. He was a member of the First church at Salem, but in 1637 joined the Antinomians and came under the ban of the Salem authorities. He was requested to sever his connection with the new church or have his arms taken away from him. He remained with the new faith and gave up his gun to Lieutenant Danforth. Later he was banished for a time for sheltering the persecuted Quakers. [source]6) Rosenbergers and Fretzes
Henry Rosenberger (1685-1745) left Germany and arrived in Franconia, Pennsylvania prior to 1729.
Hans (Weaver John) Fretz (1704-1772) left Alsace, Germany and arrived in Bucks County, Pennsylvania approximately 1720.
Their children, Mark Fretz and Elizabeth Rosenberger, were married on May 11, 1773. [source]
[The above list revised from a post I wrote last year]
As for ancestors alive between 1775-1789, the Swayzes and Van Everys ended up Loyalists, and fled to Canada afterwards. The Fretzes and Rosenbergers were Pennsylvania Mennonites, and I've found no evidence that they violated their commitment to peace and took either side.
I still had some Denyer ancestors living in England at the time, though I'm unsure if any were Redcoats.
My paternal ancestors, and half my maternal ancestors were all situated in Eastern and Central Europe (Poland, Lithuania, Ukraine, Transylvania) and were likely mostly oblivious to the war. Of course, the Polish general, Casimir Pulaski, 'Father of the American Cavalry,' came from Warka, Poland, as did my Newmark ancestors.
I have one branch I haven't yet researched far enough to ascertain where they were in the 18th century, and that is the ancestors of my maternal great great granmother, Sarah (Hartley) Denyer. So there is still some hope I may someday find a truly Patriotic ancestor.
