There were many 'plantations' of people to Ireland, Surnames from Europe/Flemish many went to England first and then often pushed out to Ireland such as the Hugenots. There were a lot of Scot plantations as well as the British landowners considered them better farmers, plus they were protestant. Perhaps in this case they needed weavers/cloth workers.
Munster was a Province one of the earliest divisions in Ireland, there were also Ulster plantations so I think they are referring to that rather than an estate of place. You can read a little about Munster as a Province on
www.failteromhat.com for example it was the largest of the 4 Provinces, included Waterford, Tipperary, Cork, Limerick, Clare and Kerry.
I think the library would be a good place to start, perhaps concentration on Irish books stores that sell on line. Eneclann, Four Courts press.
Derrick Huberts is he one of the flemish settlers? or author or land owner? Certain sounds like a Norman/English name, they invaded England from France and then would of assimulated and later made it to Ireland by plantation. May have been a de or du in Europe. Certainly Derrick is English. Purchasing books can be disappointing so libraries are sometimes the cheaper and less disappointing research.
