Hi Edward,
I just got married last month, my husband is from Shoeburryness which is next door to Southend. I was looking to see where the name came from when I came accross your e-mail. Unfortunately my husband is working away at the moment, his e-mail add is jonjemson@hotmail.com, it is a very unusual surname, I had never heard of it untill i met my husband so I hope you have some luck.
yours
Jakkie.
