Catholic Conservative backbencher Jacob Rees-Mogg recently announced the birth of a sixth child, whose name is drawn from an array of historical Catholic figures.
A picture posted on Instagram showed the North East Somerset MP dressed in a suit and tie cradling his new-born son, Sixtus Dominic Boniface Christopher.
The choice of name is likely to prompt some debate, as baby-name books say that it is derived from a Greek name Xystus, meaning ‘polished’, and should not be confused with the Latin name Sextus, meaning sixth.
However, the sixth pope after St Peter took the name Sixtus, leading some to believe there is a link with the number.
A further four Roman Catholic popes have been called Sixtus, most recently Sixtus V, consecrated in 1567.
Mr Rees-Mogg also appears to have been inspired by his faith in the choice of his son’s middle names – Dominic was the founder of a religious order, while Boniface was the name taken by nine popes and Christopher is the patron saint of travellers.
Part of the MP’s wedding ceremony to his wife Helena de Chair in Canterbury Cathedral in 2007 included a Tridentine mass in ecclesiastical Latin.
One social media user, davieboy1, commented: ‘How wonderful, congratulations!!! Now let’s get Sixtus and the others into number 10!’
The Eton and Oxford educated MP first started posting photos on Instagram during the general election campaign.
He now has 22,000 followers, 4,100 more than Theresa May, and his other children Peter, Mary, Thomas, Anselm and Alfred have all appeared in pictures on his feed.
