Our Hoogendijk family – from the villages of Stormpolder, Capelle aan den IJssel and Ouderkerk aan den IJssel (ZH) – is not the only Hoogendijk-family that exists or has existed. In-depth research by several researchers has learned that there are at least 19 other families in the world which have a comparable last name but are not biologically connected to our earliest forefathers. There are however some relations or connections. All those families originate from The Netherlands which is logic since this familyname is a so called toponym that has a obvious relation with The Netherlands / Low Countries (“Hoogendijk” in Dutch means “High Dike” in English).
Below is indicated where the “other” Hoogendijk-families come from and where more information can be found. In chronological order:
