The family don't appear as far as I could see in the Huguenot Society publication Le livre de Tresmoignanges de L'Eglise de Threadneedle Street 1669-1789 when I had a quick look at my CD copy. There is a Catherine Hantot who joined on 26 March 1758 but it doesn't say where her Tresmoignanges was from or where she was from. It could be a mispelling or it could be another person entirely.
Its possible they attended one of the other churches whose Tresmoignanges records don't survive, although the 1760s is pretty late for Huguenot migration so its possible they never joined the church and started attending one of the parish churches instead. Have you any evidence they did actually attend any of the French Protestant churches in London? If they only married/baptised their children in the parish churches, its unlikely they may ever have attended one of them.
One of my Huguenot ancestors did join the Threadneedle Street French Church in the 1740s but by the 1760s was using Christ Church Spitalfields and Bethnal Green St Matthew, as baptisms/marriages/burials happen there.
