Hi
No I am not sure he was still alive. I only have his name from marriage of his daughter Emma to John Aslett at Southwark in 1850. IGI shows a Emma Ainsworth with parents John and Charlotte, chr. 6 Jan 1828 at Langford, Beds.
Census for 1871 shows her as Emma Aslett and born Langford, Beds.
John Ainsworth marr Charlotte Squire 4 Feb 1827 at Langford from IGI.
I have found nothing on this John Ainsworth with wife Charlotte as yet and had been hoping he was alive in 1861.
I suppose next is to look at 1851 census in Langford though there may be a Charlotte Ainsworth on 1861 census if he had died.
I will also try Southwark in case he moved south.
THanks
