My ancestor Frederick William Grey (b. 1848 Tetbury, Gloucestershire) was listed in the 1871 census (Gillingham, Kent) and on his daughter's 1874 birth certificate (Hereford) as a private in the 2nd Battalion 23 Welsh Fusiliers. I can't find any other information on him (or his wife Elizabeth, daughters Olive & Gertrude)until they all appear in Canada in 1891.
Any suggestions on how I might find him during those years would be greatly appreciated.
