I have found the Arthur Eccleston Causton who came from Sudbury Suffolk England and have his ancestry back to 1775. Arthur's brother Charles Henry also came to Canada. Can send GEDCOM if you can read it or printed chart by snail mail if you let me have your adress. Alternatively you can look at this data on my web site at www.btinternet.com/~john.causton in the searchable database.
Could I please have any dates and places of birth, marriage and death as appropriate for your branch.
This branch is also being researched by Jan Reed at reeds@tiscali.co.uk who I am sure would like to hear from you

best wishes

John Causton
