George Haws Feltus

George Haws Feltus (1868–1936) was an American author and clergyman whose surviving works show a strong interest in biography, religion, and family history. He is credited as the author of Samuel Reynolds House of Siam: Pioneer Medical Missionary, 1847–1876, published in 1924, and The Feltus Family Book, a privately printed genealogy published in 1917.

His writing suggests a patient, documentary style. In The Feltus Family Book, he combined a biographical sketch of the Rev. Henry James Feltus with a record of descendants, while his later book turned to the life and work of a Presbyterian medical missionary in Siam, now Thailand.

Although not widely known today, Feltus's books remain useful to readers interested in missionary biography, church history, and genealogy. The record of his publications, along with memorial and library catalog entries, places him firmly among the many lesser-known writers whose work preserved stories that might otherwise have been lost.
