Morning John, insomnia?
No, I think he's the son of John Lugsden, baptised 1774 aged 4, son of William and Mary (Sumpter) Lugsden. This John age 33 was living in Colmworth in the 1803 Muster List with 4 children under 10, but none of them were baptised, at least not in the established church. I'm trying to piece them together at the moment.
There's also a George Lugsden 64 in Kimbolton in 1861 born in Henlow. Where he sprung from I've no idea! Not baptised, inevitably. Perhaps he's the George born 1797 at Pertenhall who you found in a non conformist register. Possibly his parents stayed on in Henlow for a few months after their marriage. Can't find him in 1841/51
I don't think I've seen a family where so few were baptised.
