Willow,
Ernest, George and James are on CWGC Web Site (
http://www.cwgc.org/cwgcinternet/search.aspx) Edward is the only one of the four named in the link that isn't there.
Your dates for the children of William, brother of Elizabeth need checking I think, this is my information on William Colley:
Wife - Eliza Hooper - Married 12.7.1847 Claines Worcester
Children I know as follows:
Christopher Colley Born 1849
Harriet Colley born 1851
Joseph Colley Born 1853
Edwin Colley Born 1855
Phoebe Colley Born 1858
Alice Colley Born 1860
William Henry Colley Born 1867 Died 1868
Thomas Colley Born 1847 Died at birth
Charlotte Colley Born 1865 Died at birth
I have Eliza Colley as a widow in 1871, I think she was a Pauper in a workhouse but again I can't read my own writing!!but her occupation is Gloveress which is as previous census information in 1851 & 1861.
Are your dates for William Colley's sons too late? Maybe it's me?
Cheers
DTR
