Hello Carole, My daughter contacted you, but it was quite a while ago.
One of my dearest friends who lives way upstate New York has Rossley descent ass follows:
Generation #1 Her mother (still living) : Marjorie Rossley, born in Worcester,MA
Generation #2 Robert E. Rossley b.Oct. 19,1894, also of Worcester,MA
Generation #3 William A. Rossley b.Dec. 1864 Halifax, Nova Scotia
Generation #4 Thomas Rossley (as you've confirmed) b.May 8,1824 in Scotland. I have his deathdate as May 22,1908.
Generation #5 James Rossley b.1798 in Scotland
Perhaps we can help eachother. If we are able to establish that I'll have to send my friend an E-mail to let her know.
Thank you in advance, Linda Sawyer
