Hi, I am Colin Dugan from Australia and I had a great aunty Ellen Dugan married an Ebenezer Jones at Yankalilla in South Australia during 1877. Thomas Jones born in 1816 and his wife Janet Powell born in 1822 arrived in Australia from Monmouthshire, Wales with 3 children and continued to produce more children. Ebenezer born 1854 (obviously a junior version of your Ebenezer) was the 4th child which was the first Australian born child. I know the names of all the children and I know my relative married Ebenezer but it stops there in a dead end. Good luck,
Colin.
