Looking for info on my great-great-grandparents and their children. John Monson was born on 18 Oct 1831, died 11 Jul 1920. Christine was born on 4 Jul 1836 and died on 9 Jul 1911. Christine's maiden name may have been Persdotter. Lived in Chicago area and northwestern PA. They had 14 children including Gust, Emma, Hattie, Anna, Hilma, Charles, Hannah, Amanda, and twins Hilda (Ida) and Augusta. Any info would be appreciated.
