I am related to Grace "Ethel" Briggs and Harold & Helen Whitney. Ethel later married Raleigh Brown.
My Mom is Harriet Briggs Greenacre and Ethel, her aunt, was Mom's father's sister. I met Ethel as late as 1963.
Edward Whitney died in 1916 but I have no death date for Harold. I have some photos and other family information.
Hope I hear from you.
