Hi Eric,
The LDS site offers up the following IGI records for the CAHILL family :
John CAHILL m. 8 Sept 1829 in Grahamstown, Mary Ann BROWN
children of this couple
i. John CAHILL b. 29 Oct 1839 d. 15 June 1879 m. 1864 in King Williams Town, Anne Jane GIBSON
ii. Catherine CAHILL b. abt 1841
Children of John CAHILL and Anne Jane:
a. Elizabeth Ann CAHILL b. 6 Oct 1865
b. Florence CAHILL chr. 20 Aug 1868
c. Catherine Mary CAHILL b. 25 April 1871 d. 1960 m. 11 Mar 1891 in East London, Alfred Ernest SHOOTER
d. Margaret Louisa CAHILL b. 28 Oct 1873
Further :
There is a Michael CAHILL b. abt 1822 and Susannah ? who had a number of children , including Michael Alexander CAHILL b. Feb 1858 , who married Amelia MULROY. This family lived in Fort Beaufort and later also in King William's Town ... could well be a link to *your* CAHILL family above.
OH AND!! ....
I've just found a christening record posted to the Rootsweb mailing list by the transcriber, Nolene Lossau ... for a John Henry CAHILL b. 29 Oct 1839 and christened 19 Nov 1839 at the Fort Beaufort Wesleyan Methodist. The record is posted as :
24 CAHILL John Henry
John and Enory?? Of 75th Reg
1839/10/29
1839/11/19
and can be found at
http://listsearches.rootsweb.com/cgi-bin/ifetch2?/u1/textindices/S/SOUTH-AFRICA-IMMIGRANTS-BRITISH+2003+625819639162+F"Enory??" could well be Mary and the birth dates seem to tie up to the John CAHILL detailed on the IGI. It seems John Snr. was with the 75th regiment ... possibly went to the Cape as a soldier?
A King William's Town christening record, transcribed and uploaded to the same list by Ellen Stanton, reveals that John Jnr. seemed to have died in 1873-1874
Entry #99
Child: Margaret Louisa CAHILL
Parents: John (now deceased) and Ann Jane
Born: 10/28/1873
Baptized: 7/16/1874
Search the Rootsweb South Africa Mailing list archives for other information. There appears to also be a list member (Ina) who is researching the CAHILL family from that area too ... . her email address will be in the archives, with one of her messages.
Good Luck!
