My second Where in the World post is for Sarah Lilla Watt, who married Harry Glover.  Sarah Lilla Watt Glover is my paternal grandmother.  She went by Lilla most of her life.  She can be found in the census with the names:  Sarah L. Watt, Lilia Watt, Lilla Glover, and Lilla D. Glover.  I expect her to be in the 1940 Census in Hazel Park, Oakland, Michigan with her husband, Harry, and son, Bruce.
