It's like a disease isn't it! Despite not having the time at all, I simply had to work out the link, and I think it is this.. I have a huge quantity of information, which, as I said, really needs to be sifted through. I cannot vouch for the accuracy of any of it because I have done no research at all, but it is so detailed that for the most part, I am assuming it is correct, and some things crop up from different sources so either it's correct or just repeated family lagend!
In 1719 Thomas Ashwin of Tower Hill, Bidford married Hester Manley of Crowle, Worc.
Their fist son, Manley, born the year of their mariage, married Mary Godfrey or Godfree in 1746. Their first son, Thomas married Phoebe Cormel in 1783 and she gave birth to 10 children of which your Edward is one.
However Thomas Ashwin and Hester Manley had 6 children. Their second son Thomas, baptised 1727, married Anne Smith of Littleton. They had 5 children. The eldest son, Thomas, born 1753 married Mary Price. He was a Magistrate and was killed in the Priestley riots in Birmingham on August 12, 1791.
Thomas and Mary had 8 children. I have details on all of them, but I am descended from their second son, Thomas Price born January 22, 1777, died blind at the age of 66 in Prestbury where he lived with two maiden sisters,Eleanor and Elizabeth. In 1804 he had married Grace, daughter of William and Sarah Jenkin of Truro. They were a Quaker family. Thomas and Grace had 7 children.
Their third child, Alfred Jenkin, born Cheltenham April 12, 1814 was an accountant. His first marriage to someone as yet unknown, produced two children, Edward Marston and Alfred Gordon. It may well have been that his first wife was a Marston because this name enters the family for the first time here. Alfred Gordon was born in Cornwall in 1843 and drowned off Cape Horn in his early 20's. I am descended from Edward Marston. Incidentally Alfred Jenkin went on to marry a second time with Susan Johnson Brick and had a whole lot more children, of which the eldest has left handwritten books about his experiences exploring the centre of Australia.
Anyway, Edward Marston,born 1845 in Cornwall went to Australia at the age of 3, presumably with his father, but this has never been researched I think. He married Susannah Tapley in 1873. The Tapleys were a well known Adelaide family after whom Tapley's Hill is named. Edward Marston bought land on the seafont at the Semaphore, then very fashionable, in 1878 and in 1884 he built a large house. He and Susannah had 4 children of which my grandmother, Ethel Maud, born 1874 was the eldest. Milford born 1876 dropped dead in the street leaving his wife Nell with 2 sons. I do not know them at all. Arthur Malcolm was born in 1778 and married Mary MacDiarmid. They had two daughters, Mary and Margaret, both of whom married and had children, all of whom still live in Adelaide to my knowledge. I have been living in France for 33 years but I have seen them occasionally. Ethel Maud married the Reverend Wilfrid Walmsley Nicholson, whom she happened to meet in Adelaide,in London, and they moved to Thorneyburn in the very north of England where my father, Bryan Walmsley was born. Their second son, Edward Marston Ashwin was born in Askam Richard, where their father died at the age of 56, leaving Ethel with 2 boys 7 and 12. She decided to return to Adelaide but contracted tuberculosis on the boat and died 6 years later,also at the age of 56. Edward married and had 3 daughters, all of whom have married and had children, but he also died at the age of 56. When my father turned 56 he had a party, although he did not know his brother's fate at that stage!! I see all Edward's children and the eldest is coming to my daughter's wedding. I married a Dutchman and came to France. Sadly I was widowed at the same age as Ethel, but instead of having 2 sons, I have 2 daughters, although they were the same age as Ethel's sons when their father died.
I hope you can wade your way through this! As I said, I have masses and masses of stuff but not very close to either of us, but my goodness, there are a lot of Ashwins around the world!
