Hello
My name is Claire Louise Warnock, I am the Great Granddaughter of Robert John Warnock and Margaret Walker

I believe you were researching this family
"Erected by E.S.D Warnock Ballywalter in mem of her beloved son Robert james Warnock born 6 Feb 1871 died 22 Sept 1898, onlu son of the late Robert Warnock Ballyeasborough. Also her daughter Louisa Evans died 1 April 1923, interred in Whitechurch Cemetery. * the above E.s.D Warnock died 9 May 1955".
It so happens that I am Elizabeth Sarah Douglas Warnock's Great Niece

I believe there maybe a mistake because the one I found was:
"WARNOCK
Erec. by E.S.D. Warnock Ballywalter in mem. of her beloved husband Robert James Warnock born 6 Feb. 1871 died 22 Sept. 1898, only son of the late Robert Warnock Ballyeasborough.
Also her daughter Louisa EVANS died 1 April 1923, interred in Whitechurch Cemetery. The above E.S.D. Warnock died 9 May 1955".
Louisa Evans was my 1st Cousin 3 times removed
Please feel free to contact me if you wish

I hope this helps
