Hello Werner Krull from South Africa. I am related to Betty Krull's husbandwhom is my direct cousin, and have I have not seen in 40 years. I recently picked-up contact with them through GenForum. Yes, there is indeed a Coat of Arms of the stam of Krull Mecklenburgh (Schwerin), itdisplays a shield with 3 stars across. You may find it in the "RIETSTAP'S ARMORAL GENERAL" perhaps to locate in your local library. Although RIETSTAP is called unreliable by some (unhappy) sources. If you are interested, I will scan it for you. Just send me your E-mail address.
