When we first registered our affix, with the Canadian KC, living out there at the time, we used the Roman name of the town we lived close to in the UK. Sadly, as there is no reciprocal agreement between the CKC and the UK KC, the name we chose had been registered in the UK by other breeders, different breed. So when we returned to the UK, we had to choose another name. Those hounds we came back with retained our Canadian affix and ever since, I have always felt we were our original name!! Actually I wrote to the people involved to see if they were still active, using the first name and got a very rude letter back saying they were happy the KC was doing it's job protecting their affix BUT that if we wanted to pay them a 4-figure sum, they'd relinquish it!! Hum.
I do think this is something way too personal to suggest a name for you - many people do use significant place names, or a mix of perhaps 2 people involved, if this applies. I imagine it's getting increasingly difficult to find a unique name, given how many are registered.
