It’s not for me or anyone else to say Hyland is or is not genetically connected/related to the Whelan/Phelan etc...
I’ve seen a few origins for the surname;
From the Irish Times Surname search;(http://www.irishtime...cestor/surname/) Numerous: all areas, particularly S Midlands. Ir. Ó h-Aoláin; originally Ó Faoláin, (Whelan). The name occurs in England as Hayland and this may the origin of some of those in Ulster. SI. SI; "MacLysaght, Edward, Surnames of Ireland, Dublin, 1985"
From a Hyland website; (http://web.archive.o...ogy/Hyland.html) The name Hyland comes from the Irish name O hAoileáin, which is usually a form of O Faoláin, from the Irish word faol, meaning wolf. Other anglicisations of the same name are Whelan and Phelan.
There are certainly many Hylands in Ireland.
I have also seen that Hyland/Hayland can be English, but it is from a different origin, and might be those mentioned by MacLysaght as being in Ulster.
I welcome all surname variants,and if someone wants to join our Whelan/Phelan/Whalen group,fine,if not,then that is fine aswell.
Most surname groups do not have a single origin,the Whelan/Whalen/Phelan group certainly have 1/2 dozen different genetic origins.(Though we do have a LARGE group of Whelan/Phelan/Whalen men in"Whalen/Whelan/Phelan Group 01'.)
If a Hyland man test and feels he is not part of the Whelan/Phelan group,he can stay in the group,leave the group,and/or also join other groups,wait for more matchesand explore what other matches he has.Is that such a bad thing. I think most Hylands would like to see/know where they genetically match.
yDNA is a tool that we use to help in our genealogy.It cannot and will not tell you all the answers,but is very good in grouping people descended from a common ancestor. So we can group men into different family groups, as part of a common surname or Clan.
