Ken, other than Proni (public records office of Northern Ireland) at such an early time it is tricky, religious records are the main or the Flax Growers list 1796 etc
I tried the Registry of Deeds Project site and only one hit, in 1743 Samuel Roleston was an innkeeper in Dunluce, Antrim. This index is not complete and being done by volunteers.
If you search by previous it should appear.
You could also try the Library in Armagh or search local lhistory groups.
Should do the simple things first, McLysaghts book the Surnames of Ireland has an entry for it, Roleston / Roulston is an English Toponmymic fairly common in Antrim and Tyrone. The main family spelt Rolleston settled in Co. Armagh. temp James 1. I do not know what temp means it this context and it does not appear in the books index explanations.
