Kind of a follow on from Tomkat's thread about being unique...
You can see how far your surname has spread about the country:

Unsuprisingly for me my surname originates from Durham. Which is where my dad is from.
So mostly found in Durham in 1881, mostly found in Durham in 1998.
it's spread out a little since 1881 with people all over the country pretty much now.
Apparently there were less than 100 people with my mums name in 1998 so I can't chart that.
Very interesting
