I hope someone can help me.

I'm seeking any information at all about the family of Brigade Surgeon John Mackenzie (1833-1910) and his wife Ashton Bostock, née Gordon.

There were four children:

Ethel 'Etta' Mackenzie born about 1869 in Aldershot, Hampshire, who married the Rev George Dickson Marshall Hughes in 1898 and had three children.

Maud M. Mackenzie, born about 1878 in Aldershot, and
Grace Annie Mackenzie, born 1885 Madras.

Any information would be greatly appreciated. I am particularly interested to know if either of the two younger children married and, if so, if they had children.

Thanks, Alistair
