Bartholemew Mosse was born in Dysart, 2 km east of
Portlaoise (then called Maryborough), the fifth son of seven children born to William Mosse, a
Protestant clergyman, and Martha Boyle. Bartholomew apprenticed with Dr. John Stone as a
barber-surgeon from 1729-1733, when he passed the examination by the surgeon-general. He married Mary Elizabeth Mallory in 1734, and they had a son, Michael, who was born in 1737. While historical records are unclear, it appears that both mother and infant died shortly thereafter. In 1738, he was appointed surgeon in charge of the draft of troops to
Menorca, following which he spent time travelling through Europe. It is believed that it was during this time that he decided to focus on
midwifery, to which end he observed maternity care in
Paris, among other cities. In 1742, he married his cousin, Jane Wittingham, with whom he had two children: Charles and Jane, born in 1745 and 1746 respectively. Charles went on to became a Church of Ireland rector and served on the board of governors of the Rotunda hospital from 1769. Jane married Col. Henry Monck-Mason in 1774 and their son,
William Monck Mason, donated a portrait of Mosse based on a sketch by James Forde to the Rotunda in 1833. Mosse adopted and trained his nephew, Thomas Mosse, who went on to the appointed the chaplain of the Rotunda in 1763 and governor in 1768. ==The Dublin Lying-In Hospital==
