According to the source, “The Wittrock name was first mentioned in the village of Brockdorf, Lohne, Landkreis Vechta, Oldenburg, Prussia in the year 1593. His estimated birth year is 1560. Tax records show that here was only one farm in Brockdorf that was held in the Wittrock name. It was inherited by successive generations at least 300 years (and probably much longer), until Anton "Henry" Wittrock sold the farm in 1885.”765
