I received this information from the Presbyterian Historical Society in Ireland located in Dublin. I agree I would really like to find primary documents to prove the statement that Rev James Maxwell of Omagh Presbyterian Church ca 1699 is the son of William Of Strabane aand therefore a grandson of the Sheriff Thomas Maxwell. The secretary at the PHS said there are several references in the church records to support this.
I am hoping to continuing the search....if anybody know more please let me know.
I would nice to know if the Maxwells of Donaghmore, Ireland somehow might be connected to the Maxwells of Northern Ireland.
