Thanks for forwarding on the response from Dr Jansze.
The information I have relating to Walter Edward McCarthy (WEM) is as follows:
WEM married 13/5/1857 St Paul’s Church, Kandy, Ceylon Selina Maria Staples (born 22/3/1840 – died 16/6/1918)
Arthur Lionel McCarthy (born about 1858) Married Sophia Agnes Jacotine (Agnes Sophia Jacotine)
May Sophia McCarthy (born 17/12/1901 – Colombo, Ceylon died 24/5/1978 – Perth, Australia married 17/11/1920 St Paul’s Milagiriya, Colombo, Ceylon Joseph Maxwell Herft (born 13/3/1894 – Colombo, Ceylon)
May Sophia McCarthy is my maternal grandmother, hence the search for information on Walter Edward McCarthy.
I have no further information other than this and wouldn't mind getting as much information as Dr Jansze can (and is willing) to provide.
Please convey my most grateful thanks to Dr Jansze for providing me with some hope.
