Margaret Kelday - Margaret Kelday

My great grandmother's name was Margaret Kelday, born July 23, 1861. She was married to James Pottinger on November 26, 1884 and they had six children, After James passed away she remarried Peter Brown Miller in 1902. Her parents names wereJames Kelday and Margaret Garrioch. Just wondering if this is the same person we're talking about.
