Yes! It would seem that all the Biggleswade Haddow's stem from one George Haddow(b1760?) and Elizabeth Parrot, married in 1780 in Campton nr Shefford (about 10 miles from Biggleswade). They had 11 children. George was a scottish soldier and was posted to Shefford in the late 1770's. I have spoken to various members of my family and there is a detailed family tree on its way to me now. E-mail me if you want a copy.
