This family apparently adored the name Mary, which was passed down from Mary Shehen (Ada's grandma) to Mary Slatter (Ada's mom) and then to both Mary and Adelaide Mary Ann Slatter. That's where the reign of Mary ended, however.
Born in Whitechapel, London, Adelaide Mary Ann Slatter moved to Ohio about 1889 and married James Sills Baker in 1895 in Cuyahoga County (Cleveland). Ada and James relocated to Toledo for a time, then back to Cleveland. I haven't found James's death date/place. Ada was widowed, later died in Cook County, Illinois--what was she doing there?
Ada and James Baker had 2 children, Dorothy Louise and Edith Eleanor.
The photo at left shows my late father-in-law Edgar James Wood, in Cleveland, with cousins Dorothy and Edith (we think).
The second marriage of Edith Baker (1901-1989) was in 1948 in Cleveland to Charles C. "Buck" Wise (1895-1963). He had a daughter from his first marriage, Janice Wise (1927-1988).
Dorothy Baker (1897-1981) married Alfred Henry Nicholas (1899-1986). I haven't yet located Dorothy's three children (Madelyn Nicholas, Joan Nicholas, and Alfred Nicholas). Are you out there?
