There is also a village named Wakefield near Shrule, Co. Mayo although the village is actually in Co. Galway. As you probably know there were Wakefields listed in the 1901 and 1911 Irish Census. http://www.census.nationalarchives.ie/search/
in the same area. There's at least one Wakefield still there as seen in http://www.eircomphonebook.ie
residential phone numbers (enter Wakefield - County Galway).
For landed estates in Galway look here, http://landedestates.nuigalway.ie:8080/LandedEstates/jsp/
I didn't see Wakefield but Wade is there.
There are 154 entries of Galway Wakefields in /www.findmypast.ie(pay
site)most are petty sessions court entries where you can learn a lot about your family. Lots of entries for the Wades in there also.
Incidentally, I find it very interesting that the four brothers struck out against Catholic rule in the late 1700's...what Catholic rule? The Catholics ruled nothing and with rare exception couldn't own property, could hardly practice their religion or attend school. Just wondering!
Anyway, have fun, there's tons of information out there for you!
