I have only just started researching, but I have found a link with you. My great-great-grandfather was Thomas Dumbrell, born in Horsted Keynes abt 1813. (Dembvell is the mistranscribed census name used, although I have posted a correction to Dumbrell) In 1841 and 51 he is living in Scaynes Hill near Lindfield. He was a blacksmith.
His son. Philip, became a carpenter and moved to Brighton where his son, James, my great-grandfather was born in 1863. James emigrated to Australia in the early 1880s, and married widow Mercy Ransley (previously from Brighton, nee Chatfield). She was 20 years older than he, and they had two daughters, Jessie Rose (died aged 1), and my grandmother, Louisa Matilda.
I am looking for relatives of the Dumbrell family of Lindfield.
Best wishes,
Dianne.
