I am from New Zealand and have started investigating my family tree. I obtained from a relation a book from family heritage international dated 1988 giving some details of the Adler name and in the book is a Adler coat of arms. How genuine it is I dont know. Some of the deatils they quote is "it is officially documented in the Rietstap Armorial General" They discibe the the colors as "divided vertically; the first blue, with a black eagle; the second silver, with five black diagonal Bands; the upper third (chief) of the shield red, placed above the division and charged with two silver swords with gold hilts, placed across diagonally.I hope this is of assistance to you. Perhaps you can help me. I need to know of any ancestors from germany who may have immigrated to Australia or New Zealand between 1850 and 1900. Great to make contact.
