Duignan/Peyton Family

My paternal grandmother had an anglisised surname of Dagnall, which I believe was originally Duignan and was born in Warrington Lancs in 1888. Her mother was Bridget nee Peyton from I believe Tibohine. The family came to England sometime in the 1870 s. Two of her siblings are shown as born in Ireland James and Maggie. I would be interested to find out more.
