Hi Sharon
I found a marriage of Charles Higham to Margaret Ainsworth:
This was on the Lancashire Online Parish Clerk web site
The marriage took place at St John, Preston, Lancashire on 23 August 1856.
Charles was a Painter.
The marriage certificate will show Charles' age and if he was a widower and this may help to determine if it is the same Charles Hyam found with wife Ellen in 1851, although I think it is unlikely the same Charles.
It would appear that Charles and Margaret might have had a son named Thomas baptised 12 April 1857. This was also on the Lancashire Online Parish Clerk web site, Source shown as LDS film 93989. Birth certificate will determine if father changed his occupation to publican.
I found a death for a Margaret Higham in Preston, 1859, age 28. There were others around this time in Lancs and of various ages but this is the most likely.
This was also on the Lancashire Online Parish Clerk web site.
The death certificate would indicate if she was the wife of Charles.
I found a marriage of a Charles Higham to an Ellen Taylor:
Our Lady & St. Nicholas & St. Anne, Liverpool, in 1861
This was in an index on
www.LancashireBMD.org.uk, no other details
Again, the marriage certificate should indicate age and if he was a widower.
I also don't know if this Charles and Ellen are the parents of Sarah but it is possible since she was baptised in Liverpool in 1865.
You will note that the marriage of Charles and Ellen in Liverpool took place in 1861, so it is likely not the same couple that you found in 1851 census in Hadley Green, although could be the same Charles that was previously married to Margaret.
