Mary Sandhurst/Chapman

Hi
I have Mary Sadhurst married John Chapman 23/2/1851 and they appear on the 1851 census as lodgers.
In the 1861 John is lodging with relatives but there is no sign of Mary.
John then marries Eliza Mylchreest in 1863 and they appear in susequent census.
My question is what happened to Mary? I have had a look at Brians site and found nothing. Also did they have any children.
Thanks
Eric
