Welcome to willighan.co.uk - home of the Willighan family tree
The Willighan surname is more than likely a derivative of the Irish clan, Hoolahan. I am led to believe that over the years, a branch of the Hoolahan tree has manifested itself into Willighan.
Houlahan originally appeared in Gaelic as O hUallachain, which is derived from the word "uallach", which means proud. Other spelling variations include Holohan, Hoolohan, Houlihan, Whoolahan and many more. It was first found in the kingdom of Thomond (which included Clare, Limerick, North Tipperary and part of Offaly), where they held a family seat from ancient times.
I can trace the Willighan name back to the Sion Mills and Castlederg areas of County Tyrone in the 1901 and 1911 census. Even so, within a short distance, there are records of the names Woolahan, Woullaghan, Willaghan and Willaughan.
After contacting the Place Names Dept of Queens University of Belfast, there is also a very small possibility the surname Willighan could be derived from Mulligan (Ui Mhaolachain). See the "Derrywilligan" page on the index for more information.
To the right is the Hoolahan family crest, and in time, I hope to be able to construct a Willighan crest. Any questions, email firstname.lastname@example.org
