Hi, Pat,
I know it's a while since you posted your request, but I have some info which may interest you. I've only just joined Rootsweb, so can't PM you. (Apologies to mods - realise that some of which follows is "off-thread")
Your William Hayes isn’t on the 1841 census because the enumerator missed a couple of houses! However, he is in Trade directories. In 1841 listed as Fanlight maker at 1, Pindar Place. (Earliest entry I have found for him is 1833, at another address in St Pancras area.)
I have an ancestor - Edward Hayes - living nearby in 1841, whose occupation (on census) is given as fanlight (something illegible), so it’s a reasonable assumption that Edward worked for William in 1841 and that the two were related. Edward used the middle name Crundwell and was born around 1814, but I haven’t found a birth record. Does this tie-in to anything you have?
Have also found census records for a John Hayes who looks like William's father. (Have read your posting on Oxford Wills thread.) Do you want details? Also later Census details for William, including his second wife (Rose) and family.
Jo
