Ok, I've added one more generation back but have, quite literally, hit a wall! His name is Thomas Wall from Somersetshire in the UK. So giving 25 years per generation this would put him being born in the mid 1500's, well before the invention of the telescope. All very interesting - for me anyway!
It's just occurred to me that besides astronomy, I also enjoy palaeontology and now looking back at my family tree. Does this smack of trying to work out where I'm from, how did I get here?
Cheers,
Mario
