Dear Realestatenovelist,
You can search the LDS FamilySearch site for free, both for the <1877> birth of Mary (Kathleen/Catherine? you wrote both names) Nolan and the marriage of her parents Jack (whose name was probably JOHN) and Jane Jewell. Keep in mind that Jane's full name might have been Mary Jane or Eliza Jane or a name like that, and she could be indexed as Mary/Eliza/etc.
Check also the IFHF databases, which aren't expensive if you find a birth or marriage of interest and want to order it. You can search for John and Jane's marriage (before 1877) and any Nolan births in Co. Antrim to a father named Jack/John Nolan and a mother named Jane. Or search for Mary's circa 1877 birth in all Ireland, and her siblings' births within about 10 years of that date. In fact, 3 "hits" come up when you run a search for Noland children's births between 1870-1880 to parents named John & Jane in "all counties". The indexes are FREE and you only pay to view a full record if you want all the details.
Emerald Ancestors is another site with both civil registrations and church records, though not as many as IFHF. I don't see a birth for Mary Nolan or marriage for Jane Jewell on any of the EA lists (or variant spellings) but there are various "John Nolan" men (Noland/Nolen/etc.).
Also search the 1901 census for Nolans and Jewells, to see which were in Belfast and in that area in general.
Search death records of John/Jack and Jane Nolan(d) in the Belfast area after 1877.
Ireland, Civil Registration Indexes, 1845-1958
John Nolan
birth: 1844
death: Apr-Jun 1906 Belfast
Coordinating this with the 1901 census, there's a John Nolan living in Belfast. He's age 60, widowed, with several adult children. All are Roman Catholic. This is probably the man who died in 1906.
Although your gr-gr-grandmother was said to be Church of England, I wouldn't discount other religions back home in Ireland. A bride or groom sometimes changed their religious denomination when marrying.
I hope this helps,
Annie
