I do not know if this is your Grace, but I have a Grace Acker, born about 1885 to Elias Acker and MAry Catherine Howe. Her sister, Maud was my great grandmother. My Grace married a James Samuels, who apparently died. She was also married to a Frank Brightman and they lived in Sandusky, OH. I have more information on the family, a little on Grace. Please let me know.
