Thanks ever so much for all your feedback, it is much appreciated

. Please see further info:-
Marriage Banns for James S and Catherine T were read in Moneydie and Methven.
I have details of the following children:-
Christian - born Moneydie 1821 (SP)
Elspeth - born Methven 1825 (no birth record)
Janet Peddie - born Fowlis Wester 1828 (SP)
William - born Redgorton c1832 (no birth record)
Helen - born Methven 1833 (no birth record)
John - born Fowlis Wester 1835 (SP)
James - born Redgorton 1841 (SP)
They're definitely resident in Crossgates, Redgorton until 1849.
William's marriage certificate definitely states the occupation for James, and William, as Flesher, not Slater.
Catherine was definitely born in Moneydie in 1799, not Blair Atholl.
I have considered the possibility that James, Catherine and James junior may have emigrated to Australia after 1849 but have been unable to find any evidence to support this.
I know that Elspeth, after her marriage to Angus McIntosh, lived in Perth until at least 1891.
John died in 1869 in Logiealmond and William died in 1862 in Crieff.
Many thanks
