Friedrich may have married Gisela von Langenselbold-Gelnhausen instead. Gisela's first marriage may have been to one of the first counts of Tecklenburg. Note that she was very young when she had her children. German Wikipedia has that Ekbert von Tecklenburg was her son, even though he was 20 years her senior.
