Not sure if you ever found what you were looking for since you posted this message but I thought I would send you this in case you hadn't. I am not related to this family.
Johannes (John) Thijses Dijkstra, was born 8 June 1868 in Lioessens, County Oostdongeradeel, Friesland, the Netherlands; son of Thijs Minnes Dijkstra and Baukje Hendriks Elzinga (Elsinga). On 22 February 1896 in Tippecanoe County, Indiana, he married Pietje (Nellie) Klases Hanstra. Pietje was born on 20 July 1874 in Stiens, County of Leeuwarderadeel, Friesland, the Netherlands; daughter of Klaas Taekes Haanstra and Geeske Pieters Ijskamp.
The father and mother of "Johannes Dijkstra/Dexter" also emigrated to Indiana. I am not sure when Thijs died but his wife (and Johannes's mother) was named "Bertha Dexter" here and died on 31 March 1915 in Fairfield Township, Indiana.
The father and mother of Pietje (Nellie) Haanstra also emigrated. Klaas (named Nicholas here), the father, died in 1912. Geeske (named Gertie here) died in 1919. In the 1900 census, Klaas and Geeske were living in Fairfield Township, Tippecanoe County, Indiana and were listed as "Nicholas and Gertie Hanstra".
There is a lot of additional information to be found in the Netherlands regarding the Dijkstra and Haanstra families. Let me know what you may want additionally of anything.
