The Belfast Telegraph of 1st May 1969 reports that a Samuel Gilmore of Rockhead, Bovedy found a fragment of a meteorite on his farm. (See attached article).
Here’s Robert & Maggie’s marriage in 1920: https://civilrecords.irishgenealogy.ie/churchrecords/images/marriage_re…
I found some probate abstracts on the PRONI wills site which may relate to your family:

The above wills are not on-line. They are held in PRONI in paper format. You need to go in person to view them or pay PRONI (or a researcher) to copy them.
In 1911 there were several Gilmore families living in Bovedy. They may all be related but work would be needed to find out how: http://www.census.nationalarchives.ie/pages/1911/Londonderry/Hervey_Hil…
The 1920 marriage certificate tells us Robert's father was James. There are 2 James G’s in the 1911 census:

I wonder if this is Robert in 1911 working away from home: http://www.census.nationalarchives.ie/pages/1911/Londonderry/The_Grove/…
This could be Robert in the 1901 census:

This may be his birth:

Parents marriage in 1876:

This looks like Robert’s mother’s death in 1902:

Robert looks to have had the following siblings:
Un-named male 1876
Thomas 1879
Elizabeth 1883
Maggie 1884
John 1886
William 1888
James 1892
Jane 1893
Annie 1896
The Gilmore/Gilmour family probably attended Bovedy Presbyterian church. PRONI has a copy of their records as follows:
Boveedy Baptisms, 1841-1929; marriages, 1842-1929; session minutes, 1842-1925; accounts, 1855-80; communicants’ roll, 1857-70 and 1888-1929.
The records aren’t on-line so far as I am aware, and so a personal visit is required to view them. If you are unable to go yourself, you could employ a researcher. Researchers in the PRONI area: http://sgni.net
GRONI is the only repository for birth, death and marriage records in what is now Northern Ireland, from 1.1.1922 onwards. (Ancestry and other websites don’t have them). Births in Northern Ireland within the past 100 years, marriages within the past 75 and deaths within the past 50 aren’t searchable on-line. They are open to the public, just not on-line. If you know all the key details eg exact date and place of birth, parents names etc, you can order a copy of a certificate from GRONI for £15. https://geni.nidirect.gov.uk But if you don’t have all the information, you need to get in touch with them to get a search done. They will do a 5 year search for £7 and if they find a matching certificate you can purchase it for £8, coming to a total of £15. It will be posted to you a few days later. You pay over the phone using a credit card. You type your number in on the phone keypad. They don’t know what it is. They won’t deal with these searches and orders by e-mail because they need you to type the credit card number in yourself. Phone: 0300 200 7890 (+44 300 200 7890 from outside the UK)
