Yes, the James Delarue I'm looking for was married to Jane Dexter (b. 1735), daughter of William and Jane Dexter of Loughborough.
James senior would have been born sometime before 1760, probably in Loughborough.
His son, James junior, was born in Loughborough in 1783 and died in 1853 in South Ockendon, Essex. He married Mary Narracott in 1821 in Nymet Tracey, Devon at the age of 38, so he may have had another wife before this. His surname was spelled De La Rue in the birth register, Delerew in the marriage register, Dilrue in the 1841 England Census, Delaine in the 1851 England Census, and Drew in the burial register.
