Looking for relatives of Peter and Mary Simpson (Pehr & Maria Gertrude Simonsson). Their children were Oscar (1877), Viktor(1871), Manda (1875), Lydia (1880), Lillie(1884), Alfreeda (1889), Sven Alfred (1867). My husband is descended from Sven Alfred. Would appreciate any information anyone has. Manda is not listed on the 1880 census. Had she died in childhood?
