Patrick Kiely b.1832 and Margaret Griffin b.1832 (Co. Kerry)

Looking for any info on the following :

PatricK Kiely b. 1832, Limerick ( My g-g-grandfather)  died pre-1882

Margaret Kiely ( born Grffin 1834 in Co. Kerry ) ( my g-g-grandmother) died 1882

I have fairly reliable information on 5 of their children:

Johanna Kiely b. 1853

Edmund Kiely b. 1856

Ellen Kiely b.1868

John ( k.a.Jack) Patrick Kiely b. 1869 ( my g-grandfather)

Margaret Mary Kiely b. 1878 d. 1882

The 1881 census records the family as living in st George Hanover Square at this time, and apparently John/Jack Patrick was mainly educated in London.

1882: 

• Margaret (Griffin) Kiely and Mary Margaret both died ( registered a few months apart) . A grandaughter of hers remembers being told that their deaths were caused by a runaway horse and trap.
• At the time of his mother's death, John ( Jack) Patrick Kiely had begun University, but had to leave and joined the Cape Mounted Rifles, a unit based in South Africa. He was stationed in Kokstad, Transkei, SA approx 1889

John Patrick Kiely ( while in S. Africa ) married...

Alicia Emily Mary Holmes b. 1873 King Williamstown, Cape, S. Africa

They had 14 children - my grandfather, Melville George Kiely, being one of them

John Patrick Kiely served in WW1 in France as a member of the SA Corps Sig. Coy, where he suffered a spinal injury as a result of a fall from a horse during battle. He returned  to SA, but in 1928 required spinal surgery, for which he had to return to London.  He died a few weeks later in Epsom, Surrey.

Any information on the above persons will be greatly appreciated.

Many thanks
