Jun. 11, 1947 New Holland Douglas County South Dakota, USA
Margje was the first of seven children and three daughters, named for her maternal grandmother, Margje Reinders Bakker. In May 1887 she moved from her parental home in the dairy farmers village Oldetrijne in the south of the Dutch northern province Friesland to the near by dairy farmers village Oldelamer, very probably to work as a housemaid for the almost 19 years older farmhand Johannes van der Tuin, to whom she married in May 1888. From April 1889 until September 1892 three children, Jan, Johannes and Hiltje were born in Oldelamer, house number 25/2.
On March 24, 1893 the family left their home in Oldelamer for the Dutch settlement Edgerton in Charles Mix County in southeastern South Dakota, just near and east of the Missouri River, and arrived on April 7, 1893 with the SS Veendam at the port of New York. On the same ship and with the same destination Margje's parents and siblings sailed. See further on her husband Johannes van der Tuin.
The Groens were Christian Reformed (Gereformeerd).
