Rebecca; Curious one, this.
While the above discussion seems to have pretty well confirmed this particular Street family were static, I looked the name up, simply because I knew a
Streeter and I wondered.
Book of Bob (Click the house beneath my avatar) lists STREET as being a name given by Gypsys in ESS, HAM, LDN and SRY. Nice, expectable little cluster then. One can clearly see how they spread across the borders.
But, here's the confusing thing:
Only in 1881. That would be the census, obviously. But, where did they come from? Where did they go? Were there no Gypsy Street people recorded in 1871 or 1891?

I have no answers. Curious though. Isn't it?
