Hi. Gladys Mary Greyell was my great great aunt - my grandfather's paternal aunt. She passed away before I was born. His father was, Henry John Greyell, from Enderby (later Kamloops), and he too was born in the 1890s. Today I found two photos, one dated around 1860, from Kincardine, Ontario. They are most likely Henry's father (Edward) and grandfather (Emmanuel). Here are the links:
