I'm not getting this at all, how is Catherine relevant to this topic? 

Likewise your reply #8 regarding a son Frank Christian Boyd, below is the family in 1911 that the birth registrations you posted belong to, the parents and the children were all recorded as born many miles away from the context to date in Belfast / County Antrim, how are they related to the OP's query?

Tracking back on these parents, I can see a church marriage for a James Ramsay to 'Jamima MacMurtry Christie' on 22 May 1873 in Kells Presbyterian Church, Co. Meath, bachelor James was a Steward living at Screggan, Tullamore, the son of William Ramsay a farmer, spinster Jamima was living at Rockfield, Kells, the daughter of David Christie a steward, the civil record index reference is here:

Turning to the more unusual name of the couple and bearing in mind the 'Scotland' birthplace in the 1901 and 1911 Ireland census returns, this Scottish baptism for a 'Jemima Mc Muctro Christie' looks promising: https://www.familysearch.org/ark:/61903/1:1:VQQY-213

The 1861 Scottish census has a possible candidate... https://www.familysearch.org/ark:/61903/1:1:VBHW-VSQ  ... living with parents David Christie (39 year old head gardener and forester) and Agnes and lots of siblings, the oldest sibling is 15, so parent's marriage maybe up to the mid 1840s, also a 77 year old James Christie in the household, possibly her Grandfather? The 1851 Scottish census has 29 year old David Christie with his wide Agnes and children, he was given as born in Kirriemuir, Angus - there is a possibility for him in a baptism for a David Christie at Kirriemuir on 10 November 1821 for parents James Christie and Helen McKinzie.  Might be worth pursuing this information further on the Scottish section of this forum.

I also am baffled by the Belfast births posted earlier in the thread 

Did come across brother of Mary Primrose marrying 1910 in New York- David Christie Ramsay-

Gosh so much information to explore. thank you  all very much. Unfortunately I didn't have the marriage  and was going from information sent to me so apologies not to be able to provide more. I thought Tullamore was near Newcastle in the North of Ireland so got myself very confused.Looking forward to following up your leads .
Many thanks
