I descend from Gjertrud Marie Larsdatter Sund (1797-1880), that was a sister of Niels Larsen Sund (1825-1894), that was father of Louis Sund. Gjertrud is my greatgreatgreatgrandmother (maternal line). I traced the Sund ancestors back to around 1600. I have not finished my research yet, but what I have found so far, can be seen on my website www.idestrup.dk. (Choose the Ahnentafel of my greatgrandmother Laurine Christine Poulsen ).
