Thomas A. L. Hay, son of Thomas J. and Christina (Kreidler) Hay, was born in Easton, Pennsylvania, October 27, 1864. He was educated in the public schools, and at the age of thirteen years was graduated from Easton High School. He then entered his father's employ, and until the year 1900 when his father died, they continued a close business association. In 1900 Mr. Hay retired from mercantile life and entered the public service of the county as deputy to the prothonotary's office in 1902, serving there as deputy until 1906, when he was elected prothonotary of Northampton county. Twelve years have since intervened and he still holds that office, having been three times re-elected, the prothonotary term being three years. This speaks louder than words, and is the most convincing and eloquent testimony concerning his administration of the office conferred upon him by the ballots of his fellow citizens.

Mr. Hay is a member of Dallas Lodge No. 374, Free and Accepted Masons; Easton Chapter No. 173. Royal Arch Masons; Pomp Council No. 19, Knights Templar; Rajah Temple, Nobles of the Mystic Shrine of Reading, the Tall Cedars of Lebanon, of Lebanon; Easton Lodge No. 121, Benevolent and Protective Order of Elks; Vanderveer Lodge No. 175, Independent Order of Odd Fellows; and the Jacksonian Democratic Association. He adheres to the Lutheran faith, and is affiliated with St. John's Church of Easton. In politics he is a Democrat. He married, February 21, 1896, Wilhelmina Daub of Nottingen, Germany, and they are the parents of two daughters: Christina C. and Wilhelmina M., both graduates of Easton High School. The family residence is No. 124 North Tenth Street, Easton.
