Commenting for my friend: The parents of Lucy Porter, who married Andrew Munro in Amherst, Nova Scotia, were Charles Porter and Sarah White. Charles was a tailor born in England (possibly Hull), and Sarah was a seamstress. This all comes from family word-of-mouth. My friend is a descendant of Charles & Sarah > Sabra Alice (Porter) (1859-1893, born in Amherst, NS) McDermott. So Sabra was your Lucy's sister.
