She married Robert Gladstone Innes in 1916 in Grimsby, and her father, Richard Sheppard was a Skipper RNR at that time. I have found a possible marriage for Richard in Greenock (which fits in with what I have been told) on 9th November 1883 - to Catherine Feeney.
My problem is that between this time, 1883 and the marriage of May in 1916 I can find absolutely no trace of any of them. I can understand Richard being difficult as he was a Mariner, but where the heck were Catherine and May???
I must also add, that I cannot find a birth for May Sheppard in or near 1887 either in Scotland or England, and have wondered if perhaps she was adopted, but that still doesn't explain why Catherine is also missing from the face of the earth
If anybody can help me in any shape or form, or come up with suggestions of where to look next, I would be very grateful.
