There was a significant family of the Harrison surname associated with Lisburn and with the cathedral there. For example, a daughter of Edward Harrison 1644-1700 (son of another Michael who d.1683) married Dr Jeremy Taylor, Lord Bishop of Down. There are numerous references to this particular Harrison family online and in Google Books.
I did wonder whether the Rev. Michael Harrison of Ramoan was related to that lot. However, I wouldn't have expected him to have a status of sizar at TCD, but rather of pensioner.
The following may serve only to confuse the matter further: in addition to the Alumni Dublinenses entry for Michael Harrison (1688-1765), the librarian at TCD sent me this information about one John Harrison who entered TCD on 2 October 1685, age 20:
- his father was James, "Generosus de Neaghan in Com. Dunensi" (i.e., a gentleman of Neaghan in the county of Down).
- John was born in Neaghan, co. Down.
- his status was sizar [Alison's note: so, a student could be a sizar and also the son of a gentleman...].
- his schoolmaster was Mr Harvey of Lisburn.
Upon completion of his studies at TCD, John Harrison attended Trinity College Cambridge from 1689-90, where his status was pensioner. You can search for this entry in the online version of Alumni Cantabrigienses at
http://venn.csi.cam.ac.uk/ACAD/search.html. The entry states:
Harrison, John.
Adm. pens. (age 22) at TRINITY, 01 Feb., 1689/90, from Trinity College, Dublin [Ireland].
Adm. there, 02 Oct., 1685.
S. of James. B. at Loghlin Island, Co. Down, Ireland.
School, Lisburn, Lisnagarry, Co. Antrim (Mr Rob. Harvey).
Migrated to Corpus Christi, 1690.But, the question does arise: was this John Harrison, in fact, the father of the Rev. Michael Harrison of Ramoan? Also, was there any connection between John Harrison of Lisnagarry and the line represented by Michael Harrison d. 1683, mentioned in my first paragraph above?
My advice would be to borrow a copy of Alumni Dublinenses, or borrow a microfilm copy of it through an LDS family history centre, and study all of the entries for Harrison.
I have summarized all the references that I have found, to date, with respect to Michael Harrison d.1683 in a Word document and would be happy to send that to you.
