SEE: "THE ROSENKRANS FAMILY IN EUROPE AND AMERICA" BY ALLEN ROSENKRANS 1900, PAGE 35; "This Erik, or Erichs, of Holstein, the first known head of the Danish Noble Family (in 1227) which subsequently to the name Rosenkrantz had a son named . . ." NOTE: ROSENKRANTZ (ROSE WREATH) NAME USED ON FAMILY COAT OF ARMS AFTER 1325 THEN FORMALIZED ABT 1524 WHEN NOBLE FAMILY NAMES BECAME LAW UNDER THE KING OF DENMARK. Page 26 gives the line "ERIK to HERRINGHOLM" meaning ERIK of HERRINGHOLM which is the ancestral home of the ROSENKRANDS family in Denmark. ERIK probably came from northern Denmark or Norway. According to tradition, ERIK must have been a warrior (crusader) and an ancestor of his, a MACK DONALD, of Scotland, who probably married and settled in Norway or Denmark about the year 830 AD.
The only marriage I have recorded is that of Ott Rosenkrantz and Kirsten Gyldenstierne in 1321. Are you also a Hamlet fan?
