I am curious if it is known if there is a connection between the surnames Sinnigen and Sinnige? I am researching a Helene/Helena Sinnigen/Sinigen b. July 5 1842 in Ashendorf Germany, which is in Lower Saxony and very near the border with the Netherlands. She emigrated to the US with her husband (Johan)Bernard Ahrens/Arens in 1868. Her parents were Henry Sinnigen and Susanna Avers.
