Hi Colin,
So you're chasing the night skies in Mauritius now!
I have to say I've thrown in the towel to some extent. The earliest Wm Hensh* in whom I have any confidence in admitting to my tree is the 'Keeper of Bollin Fee' (and I think, considering the line of succession within the Hensha* family, by this is meant park keeper, gamekeeper etc) who died in 1666. I suspect he was the son bp 1589 of Thomas H 'de parke' of Wilmslow.
But, to be honest, beyond that I'm not now purposefully venturing. My forays further into the past (or even forwards on occasion) have frequently given me a sore head - and not just in pursuit of Hensha*s; in all, leaving me with the feeling that I'm not just tilting at windmills, but colliding with their brick walls!
I've even fallen on stony ground - oh, what a mixing of metaphors - in trying to find any truth in the claim of my gt-grand Hensha* aunts (dtrs of James Henshaw/Mary Leah), relayed to my mother by their niece Jessie Henshaw, that they were related in some way to Henshaw of the Blind Asylum

Though I have to say Jessie, who was a stickler when it came to family facts, was somewhat sceptical [PS: and having looked again at the detail of Jessie's recollection, I think she was probably right to be!]
So I'm sticking with/at the blacksmiths and the keepers.
Best regards,
Sarah
