I am no relation to this family.
Pieter van Lieren was born 9 January 1839 in Wissenkerke, province of Zeeland, the Netherlands; son of Marinus van Lieren and Alida de Nooijer.
Sara Boot was born 21 October 1848 in Wissenkerke, province of Zeeland, the Netherlands; daughter of Cornelis Boot and Jacoba Pieternella Johannisse.
Pieter and Sara arrived in the USA in 1873. They were married in Kent County, Michigan (Kent County, Michigan Marriage Books 1867-1877, Book 4, page 92). My guess is that they were married in 1873.
Pieter was married once before. What was unusual was that his divorce from his first wife (Anna Magdalena de Ronde) was not finalized until 19 December 1873. There is no doubt in my mind that Pieter and Sara knew each other prior to leaving for America. Maybe that was the reason for Pieter's divorce from Anna? Pure speculation that there was an affair between Pieter and Sara but things do add up to that. That they took off to America together in 1873 and married here is another indication that things were happening between them before Pieter's divorce was finalized in late 1873.
In her post in 2003, Janet stated that daughter "Olive" was born in 1873. There is no doubt that she was Pieter's and Sara's first child and that she was born in 1873 or 1874. In the 1880 census, the family is living in Robinson Township, Ottawa County, Michigan. They have 4 children: "Alace", 6 (could this be "Olive"?); Cornelius, 5; Manus, 4; and Jennie, 2. I think the first daughter was named after Pieter's mom, Alida. Cornelius is named after Sara's dad, Cornelis. Manus is a derivative of Pieter's father Marinus.
At this time I do not know when Pieter died but it seems he died before the 1900 census as he is not listed on that census and Sara(h) is listed as head of household although not as a widow but still listed as married. Sara(h) is also in the 1920 census living with son Peter.
