I am running out...and late as always

But, just wanted to add this info.
I think the John Bishop, son of John and Jane Henderson, may still have been around Scotland and as such we can eliminate him from what we are looking at. Needs to be confirmed via death cert, assuming he may have died in Scotland.
This is 1841:
John Bishop 28 Meals Dealer Shopman
Margaret Bishop 28
Thomas Bishop 2
John Bishop 36 Months
https://familysearch.org/pal:/MM9.1.1/XTTQ-HR2Address: St Anchea Street Fox Lane, South Leith
I think this couple is John Bishop and Margaret Tyrie. One of their children is a daughter called Jane Henderson Bishop (the John born in 1812, his mother was Jane Henderson). Children show for this couple on Family Search.
Such interesting families, sigh, want to look more now
http://rbg-web2.rbge.org.uk/bbs/learning/bryohistory/Bygone%20Bryologists/JOHN%20BISHOP%20DUNCAN.pdf This looks to be a grandson of John Bishop and Margaret Tyrie, son of Margaret Tyrie Bishop.
I am hopeful that John Bishop's DC, born 1812, is likely to be found post 1855. Will look more later... If we can properly eliminate him, we can focus better on the John Bishop born 1809.
The family seem to be in Dalkeith, going by the children's entries, by 1851.
Will try and do more later.
