The only Gillespie mentioned in this scrapbook is Margaret Murray Gillespie, daughter of Anne Dunlop and Peter Murray. She was born in Scotland in 1844 and came with her widowed father and 12 brothers and sisters to Hamilton, Ontario, sometime after 1861 when her mother died. "Gillespie" was her married name - her husband's name isn't given. There are no photographs in this scrapbook; just a handwritten account of the Murray-Dunlop family dated 1935 and written by Beatrice Murray Dunlop, a granddaughter of Anne Dunlop and Peter Murray. The rest of the scrapbook contains newspaper clippings about various topics, none related to these families. Please let me know if this matches up with your family, and I will send more information.
I am sorry to be so late in responding to your query - hope you can still use this information.
