Yes, there is a relationship between the two. I share the same line through to Edmund Andrew van der Sluys/Vandersluys. I have listed my paternal genealogy on my facebook wall which I will copy hereunder :
My Paternal Geneaology = Father Ralph b.1918, GF Joseph b.1865, GGF Edmund b.1835 (London), GGGF John II b.1790 (Cornwall), GGGGF John b.1757 (Cornwall), GGGGGF Lambertus II b.1727 (Holland), GGGGGGF Jan II b.1700 (Holland), GGGGGGGF Lambertus b.1677 (Holland),GGGGGGGGF Jan b.1646 (Holland),GGGGGGGGGF Marten b. 1620 (Holland), GGGGGGGGGGF Abraham b. (watch this space) Haarlem. Holland
Edmund born 1835 is the Father of the person that you refer to. Hope this helps.
