Greetings heywood,
Just an update.. tracked Frank Kelly to 1871 son of William!!!
BUT a widower has 3 other sons James born abt 1861,George born abt 1864 and Frank born abt 1868. The head of the household is Sarah Mellard born 1783 . and is a widow. Interesting thing is..has William as Hus....and a widower. Think this is his mother.
Found the possible Kellys in 1861 Brampton Bierlow index as KELLEY. Sarah Kelley born 1790 Houghton Head and William Kelley son and wife Sarah Kelley born 1825 Mansfield Notts!!! Can you believe that!! No wonder she couldn't be found Yorks of Lancashire.
Of course as usual nothing is simple.. there are TWO Frank Kellys born 1867 and in the same area.Fortunately one Frank Kelly is with his parents (William and Hannah) in 1891 census and other Frank Kelly is with Daniel Lister in 1891 and 1901

Found the death of a Sarah Kelly Jun qtr 1870 age 47
So pieces SEEM to be coming together.
I thought I would obtained George Kelly's b/cert( only one fits) rather than ordering the wrong Frank.
Sooooo do you think I am on the right track?
Ta muchly
