Messenger (GB) is listed as grandsire to the mare Amazonia, in Hambletonian 10's pedigree in our library. This is according to the Wallace Register Vol.1, which was the first stud book for standardbreds in the United States (in the late 1800's). Later studies have made it uncertain that Messenger is Amazonias grandsire. For this reason we want to mention that the link we have to Messenger from Amazonia in Hambletonian 10's pedigree in our library may not be accurate (in i.e. the article about Messenger that is written by Bo Fransson, there are only three links to Messenger listed in the pedigree of Hambletonian 10 - not four as it would be if one also count the link from Amazonia).
