Hi
Just browsing the net and came across your entry for Dellaway. My maiden name is Dullaway which through miss spelling should have been Dellaway however the spelling has stuck. I descend from Thomas Dellaway one of the sons of John and Jane Dellaway whom you mentioned coming from Croydon but the line orginated from Sussex. I also live in Australia. Arthur Richard Dullaway came to Australia in 1886 and settled in Rockhampton Queensland and my grandfather Thomas came out as a child with an uncle in 1913 and first went to Rockhampton, then later settled in Sydney NSW. All the Dullaways of Croydon and most of the Dellaways of the 1800's are all related having descended from John and Jane.
I would be very happy to hear from you and pass on the info i have.
