My ancestors (Jan(John) Karel b.1816 m. Kotje (Katie) Bakelaar b.1820) imigrated from Ouddorp, ZH Netherlands to NJ in 1861 before coming to Grand Rapids, MI in 1869. Children are Gerrit, Johanna, Richard, Martin and Pieterje. Gerrit and Johanna remained out east. Gerritt americanized the last name to Karl.

Am looking for information to find out Jan (John) Karel siblings\parents.

At this point I have no knowledge of them being related to the Karel family from Holland, Ravenna, Muskegon or other Karel families in Grand Rapids.
