Thanks for the census reference - still hadn't managed to find it, will try again with that data.
As for the son's name and year of birth..... that's the bit I really don't know. My record says there was a son, and no more. I also know there must have been a son, because HIS son was my great grandfather (Frederick Seaton Burrowes - by now the surname has acquired the 'e'), but he turns up in Brazil, and I have no clue how he got there!!!! And I can't find any birth records for him to get parent's details, and I don't have an accurate estimate of his dob either, but probably somwhere 1850-1860. He may even have been born in Brazil. Oh the joys........!
Thanks for the help
