On March 1, 1888, Emma married John Charles Roe, son of Daniel B and Margaret Martha Vanderhoof Roe. Emma and John had six children; Florence (1888-1895), Stanley F (1890-1972), Harry W (1895-1966), Earl Arthur (1897-1990), Grace Wilhemia (1901-1994) and Charles Lawrence (1903-1989).

Emma A Davis was half-sister of Horace D Davis, who married Margaret Ann Roe, older sister of John Charles Roe.

Emma probably died around 1908, prior to her husband remarrying. No record or burial is currently available.
