William Heberden and Mary Wollaston
William was first married to Elizabeth, daughter of John Martin of Overbury. They married June 1752 at St Martins in the Fields, she died 26/11/1754 and was burried at Overbury.   Children:  NN ;  Thomas * 28/09/1754, sometime fellow of St Johns College Cambridge, later canon of Exeter, +17/10/1843.
William remarried 19/01/1760 to Mary Wollaston.
Children from this marriage: 
William, died soon;  William *23/03/1767, married to Elisabeth Miller (see below);  George, died unmarried 1786;  Charles, fellow of St John's College, +13/03/1796;  Mary *02/08/1763, married 17.06.1877 to George Leonard Jenyns *1764, canon of Ely, +25/02/1848;  Charlotte *24/06/1768, +05/07/1768;  Harriet, died an infant.

William Heberden had a distinguished career.¹  Entered St Saviour's Grammar School aged 7 (his father died that year) and showed prowess in Greek, latin and divinity, so that he could go 1724 to St John's College, MA in 1732, to become MD in 1739. He remained ten years at Cambridge practicing medicine, and gave an annual course on materia medica.

In 1752, this branch of the extended Heberden family had been granted a family coat of arms and crest. According to the British Herald (1830) it was borne by both (half-)brothers rev. Thomas Heberden, Canon of Exeter and M.D. William Heberden of Datchet, near Windsor (William the younger).

1746 he became fellow of the Royal College of Physicians in London, moving to London in 1748.

Heberden, who was also a classical scholar, published several papers in the Philosophical Transactions of the Royal Society; and among his noteworthy contributions to the Medical Transactions (issued, largely at his suggestion, by the College of Physicians) were papers on chickenpox (1767) and angina pectoris (1768). His Commentarii de morborum historia et curatione, the result of notes made in his pocket-book at the bedside of his patients, were published in 1802 and again in 1807. In the year following the first edition, an English translation appeared, and further publications in 1806 and 1818. The English translation is believed to be from the pen of his son, William Heberden (1767–1845; see below).

Heberden studied the painful inflammation of the finger joints, especially those toward the end of the fingers, swellings now know as due to osteoartritis. The hard bony swellings are since called Heberden Nodes (published by him as a chapter in his "Commentaries on The History and Cure of Diseases").

At the age of seventy-two he partially retired, spending his summers at a house he had taken at Windsor, but he continued to practice in London during the winter for some years longer.  William died in 1801. His tomb is in Windsor Parish Church. Mary died 22/02/1813 aged 83.

Michael Underwood and NN
Underwood was the first physician‐accoucheur to be appointed to the Royal College of Physicians in London. The same year, 1784, he published a textbook which did much to establish paediatrics as an emerging discipline in its own right. He is a relevant figure in the history of medicine and pediatrics for having given the first known description of several childhood diseases, infantile paralysis included. See Underwood Wikipedia. and M Underwood, by P.M. Dunn (2006).
Underwood was appointed physician to the Princess of Wales (wife of the future George IV), and, in 1796, attended the birth of her daughter, the Princess Charlotte.
