If the Earl Grose you refer to was Earle Mervyn Grose, s/o John Samuel Grose & Sarah E. Langford, then we're related since my gr-grandmothe was Mary Elizabeth "Minnie" Grose, a sister of John S. Grose. She married John Bannerman of Blanshard Tp., Perth County. Hamilton Hodgins of Lucan, ON did an unpublished genealogy of the Grose family starting with Charles Grose (father of Minnie & John) in 1994. There was also a genealogy for the Langford-Westman families published a couple of years ago. If you want to exchange more info on the Grose families, get in touch.
