I am researching the PIERSON family from Irelnd (the last name was spelled PEARSON in Ireland, PIERSON in USA). Samuel William PIERSON (18 Mar 1865, Castlefarm/Thomastown, Co Kildare, Ireland - 18 May 1910, Thorp/Chippewa Falls, Clark, WI) married (06 Sep 1895) Maud Francelia BANCROFT (27 Aug 1879, Bancroft, Portage, WI - 05 Jan 1984, Aberdeen, Brown, SD). After the death of Samuel, Maud married (11 May 1911) his brother, Robert PIERSON (06 Feb 1874, Castlefarm/Thomastown, Co Kildare, Ireland - 13 October 1956, Aberdeen, Brown, SD).
I am also interested in FERDIANDSEN/COFFEN genealogy. My maternal grandmother, Ella Genevieve COFFEN (22 Nov 1869, Seneca, Kossuth, IA - 01 July 1946, Aberdeen, Brown, SD) married (28 Jan 1891) John Peter FERDINANDSEN (16 Oct 1863, Copenhagen, Denmark - 8 Oct 1920, Goodridge, Pennington, MN).
On my wife's side of the family, I am interested in LOHNER, HENNIE, KIENOW and NELSON/SWANSON genealogy. My wife's maiden name is Julie Ann LOHNER. Her paternal grandfather, John Anderson LOHNER (LONAR in Norway) (1851, Sauland Telemark Norway - 1924, Waubay, Day, SD) married (in Webster, Day, SD) Anna HENNIE (1861, Skien, Norway - 1942, Waubay, Day, SD). My wife's maternal grandfather, Henry John KIENOW (15 Jul 1886, Warner, Brown, SD - 20 Mar 1947, Warner, Brown, SD) married (23 Oct 1912, Warner, Brown, SD) Julia Amanda NELSON (22 Feb 1888, Warner, Brown, SD - 13 July 1956, Aberdeen, Brown, SD). Henry's father was Ferdinand KIENOW (Pomerian Germany - Warner, Brown, South Dakota, USA) who married Amelia BORTZ (Germany - Warner, Brown, SD). Julia's father was Swan NELSON (born Nels SWANSON, 1851, Sweden - 1942, Warner, Brown, SD) who married Anna (1848, Norway - Warner, Brown, SD)
