Her husband’s name is Joseph Daley according to what I read.
I stand corrected. I had read that Kelly Ayotte had married into a French-Canadian name, and I looked into it and found that my source was a frequent poster on The Hedgehog Report (who is usually correct about these things, but apparently not this time, unless Joseph Daley is Kelly Ayotte’s second husband and she kept her first husband’s name, unlikely given her relatively young age).
