hi guy
Paid a visit to Burnley central library on your behalf this afternoon. As you would prob expect they have no register of christian names at all, so I made a quick sample check of two parish registers. One had 2 Cuthberts and the other had 1 Cuthbart ( none of these was your man by the way.) As a surname it is much more common. I found a 1740 trade directory that listed 11 Cuthberts, 2 Cuthbarts,1 Cuddbart, and 1 Cudbarts but I don't s'pos that is much help in what you are after is it?Dont really know how to answer your question, is it common in Burnley, but in growning up I knew two Cuthberts. One was our old insurance man and the other I went to school with, so I s'pos it is still crossing generations although I havnt come across it recently. Don't know if any of this helps. P.S if you get a prize for the most obscure question, maybe I deserve one for the worst answer
