Hi Theresa
I believe I have found 2 sisters for Mary Jane McDermott King from a combination of the websites AncestryIreland, Emerald Ancestors and Family Search.
Margaret McDermott (father James) married Patrick Galbraith (father Robert) in Rostrevor on 8 Sep 1865. Going by their sons’ occupations, it is possible that Patrick was a tinsmith. They had 12 children :
1. Robert, b 26 Jun 1866 in Co Down. Robert was a labourer and he married Catherine Savage (father James) in Downpatrick on 4 Feb 1906. They are living in Killough in 1911 (no children).
2. James b. 22 Oct 1867 in Co Down (possibly Kilkeel – will check that). James was a tinsmith and he married Margaret Savage (father James) on 12 Jan 1899 in Belfast. Margaret and Catherine could be sisters but you would have to get the marriage certs to find that out. They were living in Belfast in 1901 but Downpatrick in 1911. They had at least 3 children : James, Thomas and Robert. There is a Mary Jane living with them in 1901 but she may not be James’ daughter.
3. Thomas b. 26 Apr 1869 in Co Down (possibly Kilkeel). Thomas was a tinsmith and he married Sarah Kemp on 1 Dec 1898 in Newtownards, Co Down. They had 5 children : Maggie, Thomas, John, Patrick and Catherine.
4. Margaret b. 29 Jul 1870 in Garvagh, Co. Londonderry.
5. Agnes, b. 03 Apr 1873 in Bothwell, Lanarkshire, Scotland.
6. William b. 27 Apr 1875 in Co. Down. William was a tinsmith and he married a Rose (don’t have their marriage). They lived in West Belfast and had at least 12 children, 5 of whom were living in 1911 : Patrick, Agnes, William, Roseann, Mary Ellen.
7. Patrick b. 16 Feb 1877 in Armagh. Patrick was a tinsmith and he was single up to 1911. He does not appear to know where he was born as different places are given in the censes, but as this family travelled a lot and didn’t stay for very long in the one place, that is no surprise!
8. Sarah b. 24 Jan 1879 in Co Down.
9. Joseph b. 27 Oct 1880 in Ballycastle, Co Antrim.
10. John b. 1882
11. Jane b. 1884. Jane married Hugh O’Hanlon (tinsmith) in Downpatrick on 10 Oct 1904. Does not appear to have had any children.
12. Francis b. 1886
Catherine McDermott (father James) married Charles McKay (father Edward) in Rostrevor on 7 Jul 1877. I believe Charles was a sailor according to this website where the person appears to have seen the birth cert
http://freepages.genealogy.rootsweb.ancestry.com/~fremac/ireland/pafg190.htm If you click on the Notes beside Edward John’s birth you will see that her mother Sarah McDermott registered the birth.
Catherine and Charles McKay had at least 3 children (born in Newtown, Rostrevor) : James b. 5 May 1878 and Edward John b. 4 Nov 1879 and Sarah Jane b. 1892. I cannot find this family anywhere in the 1901 or 1911 census.
