Thanlks for the reminder, Jebber! I have a few like that too - I guess most of us have. But in this case the father is named and is real, he's just disappeared from the records since his son's baptism in 1810, and doesn't even get listed in the 1841 census, yet the marriage certificate doesn't say he is deceased. The son is a tailor - but maybe he didn't even know his father's trade if they were no longer in touch. If Dad had been a silk mercer during the son's childhood, he would have been selling his wares to upholsterers, so maybe the son thought that was his trade.
