Haviland identification is difficult as there are over 30,000 patterns and variations. Only about 6,000 have been identified and cataloged in the Schleiger system. Most patterns do not have factory-given names.  Some received names from later writers or in common usage. There are four major brands:

1) Haviland & Co. Limoges (H&Co.)

2) Theodore Haviland, both France and New York

3) Charles Field Haviland (CFH)

4) Johann Haviland, the later, inexpensive Bavarian china. We do not identify Johann Haviland pieces.
