Reference: In his appraisal of this tooth, Stuart M. Frank "confidently attributes" it to Caleb T. Albro of Jamestown and Portsmouth, Rhode Island, who sailed aboard the John Coggeshall of Newport from 1834 to 1847. According to Scrimshaw and Provenance: A Third Dictionary of Scrimshaw Artists written by Frank (Mystic, Ct.: Stuart M. Frank and Mystic Seaport Museum, 2013), Albro was born probably in 1816 and served on one whaling voyage.
