I have been working on this bunch, they are not our relatives who are Kuypers, but got interested in them. I have a bunch of history books from Pella, as I do have a bunch of dutch families from there.
I believe Dirk and Mrs, came in 1856, I believe they moved to kansas sometime around 1867 or beginning of 1870. Their children are not listed in the book of folks coming in the year 1856, but believe they had several children.
One girl was a Adriana "Jane" who married a Cornelis De Haan, she had a sister Ellen, I am not sure of the dutch name for Ellen.
Does this help.
