It was in this church in St Giles High Street in the West End that another significant event took place for Mary Shelley – her son William and daughter Clara Everina were baptised here on 9th March, 1818, just a couple of months after Frankenstein was first anonymously published.

The baptism took place just before Mary and her now husband, the poet Percy Bysshe Shelley, departed once again for the continent, apparently this time with no intention of returning.

In fact, the Shelleys attended three baptisms at the church that day – along with William (nicknamed “Willmouse”) and Clara, those undergoing baptism also included Allegra (at first called Alba), the daughter of Mary’s step-sister Claire Clairmont and the poet Lord Byron.

In fact, part of the group’s reason for going to Europe, along with Percy’s debts, ill-health and fears over the custody of their children, was to take Allegra to her father, Lord Byron.

The officiating churchman was said to be one Charles McCarthy.

The current font, which dates from 1810, in the church is presumably that in which they were baptised. It was installed well after the now Grade I-listed Palladian church, which is sometimes known as the “Poet’s Church”, was consecrated in 1733 (it is the third said to have been built on the site since the start of the 12th century).
