I have an ancestor named Dielman Kolb, Jr., married to an Elizabeth who has children named Henry, Elizabeth, and Jacob. This Dielman, died in 1789. A distant cousin listed this Dielman as the son of a Dielman Kolb who came to US on the Mortonhouse in 1727 (ftp://ftp.rootsweb.com/pub/usgenweb/pa/1pa/ships/1729mrtn.txt). A similar Dielman at the Kolb/Kulp/Culp site is the son of Henry Kolb.
Does anyone have a family history for either of these Dielman Kolbs? I am trying to figure out if the family tree I have is accurate or not.
Thank you for any help you can give me in this matter.
