Thank you all for your help,

I will spend some time looking at all the links.
I have narrowed the original surname I am researching down to Spanish, there's no doubt about that ,the surname is Galician,
the occupations were fruitseller/hawker.
My avatar is my gt.gt.grandmother, 1818-1906 born in Spain.
I am now curious, if they may have been Gypsies when they arrived in UK.
Thanks.

Joan
