Thank you everyone.
I'm a bit dissapointed at the plaque, I thought they were going to put both their names together on one as that's what I asked them to do. They didn't say they would put one and the top and the other at the bottom.
I was too upset to discuss it at the time but the more I see it the more I'm a bit miffed by it but I don't want to travel back to the crem as it's quite far from where I live to have it amended. Nevermind, at least I have them back.
