Hello Liz, and thank you for your help with this. The family that you mention with mum Eliza, and children Francis, Selina and Charles are from the 1841 census living in Birmingham.

On the 1851 mum Eliza has now remarried a William Lewit/Lewis and living with them in Birmingham is Harriett Whorrall. The Charles Whorrall that I am looking for is not at home with them, I am interested to know where he might be, he would be aged about 13 years.
