Thank you for the replies.
Alan, It all started with a will! The will of William Birkett of Middleriggs, Troutbeck, 1872. In the will it mentions amongst others my 3rd Great Grandfather and his siblings who were the children of James Birkett & Ann Coward of Skelwith Bridge, Cousins. James & Ann had a son James & also a William. William is not named in the will as a child of James & Ann so I presumed by the date of the will being written that he was deceased. The will also mentions a James of Grasmere and his Brother William of Crossgill Mill, Caton, Lancs. So, these two are separate people i.e., not the children of James & Ann. William of Crossgill mill inherited the family silver & more money than the others mentioned so, I think may have been a closer family member. I am trying to find out who he was! I have found what may be him on the 1841 census and all the way through his life till his death in Yorkshire. James, the Son of James & Ann of Skelwith Bridge never lived in Grasmere but I have found another James of Skelwith Bridge who married Elizabeth Harrington who did live in Grasmere. So, a candidate for these two's parents is William Birkett & Hannah Grave. In a newspaper article, it states the marriage at Grasmere, 1819, William of Skelwith Bridge. These two baptised three children at Grasmere, James 1820, John 1822, William 1824. (I have yet to trace John!). I am thinking that I need to find William's Father (William who married Hannah Grave). Hope this makes sense??
