Am posting some Turner information in case you don't already have it.
Thomas Turner m.(1868) Charlotte Gaston (details posted above)- children:
1. Mary Eliza born 1 Oct.1869
Aghadowey district, Derry2. James born 5 July 1871
Aghadowey district3. Elizabeth Ann born 28 Apr.1873 Aghadowey district, m. Samuel Neilans 4. Margaret born 26 May 1875
Dirraw district, Antrim- "Maggie" at home in 1901 census.
5. Thomas born 25 Oct.1876
Slavney?, Ballymoney district, Antrim - at home in 1901 census.
6. Charlotte born c1881 m. Henry Adams.
7. Annie born c1885 m. Hugh Clark.
Elizabeth Ann "Bessie" Turner married 1894 to Samuel Neilans and had at least 3 children.
Not sure if she's the Mary Eliza born 1869- suspect Bessie was a younger child, perhaps Mary Eliza died young.
1. Thomas born c1896- 1911 with Turner grandparents
2. Maggie born c1898- 1911 with aunt Annie Clark
3. Mary born c1903- 1911 with Turner grandparents
In 1901 the Neilans are living in Liffock-
www.census.nationalarchives.ie/pages/1901/Londonderry/Articlare/Liffock/1517051There's no trace that I can find of Samuel in 1911 census nor a death for him between 1901/1911- but the spelling of the surname might be the problem. However, Bessie Neilans' death was registered July/Sept.1910 and gives her age as 34. This is probably why the 3 children are living with relatives by the 1911 census.
Annie Turner married Hugh Clark and had 3 children by 1911 although at the time of the census only 2 daughters were living. Interestingly, both the daughters were born in Scotland. Annie's neice Maggie Neilans is also in the household.

www.census.nationalarchives.ie/pages/1911/Londonderry/Somerset/Ballyness/587772 This might be the son James Turner in 1901 and 1911 census records (should be Articlave not Articlare)- the location is close to where Bessie Neilans lived and this could be how Bessie met her husband Samuel.
