The only Thomas Lovel of a suitable age that I have been able to find was the son of Thomas and Elizabeth Lovel born 22 January 1744 and baptized at St Sepulchre Holborn 04 February 1744.
Thomas and Sarah were married at St Mary's church, Hayes, Middlesex in October 1762. (Hayes is about 17 miles to the west of Holborn.)
They subsequently had seven children baptized there.
Sarah was buried at Hayes on 7 March 1813 aged 68 so born about 1745 and Thomas was buried there on 17 August 1881, his age not given.
Known children of Thomas Lovel and Sarah Scragg, all baptized at Hayes:
