Yes ! I'll give my mind a rest off the Hood's for a while !
As I said earlier, a semi wild picture is forming that seems my fit.
John Hood being a mariner working away a lot-( John's Job links him as a mariner to ports like Wearmouth, Selby, London ports), -----if ? in this scenario mother Elizabeth Gibson (Hood) died just after this George Hood bapt 1786 in Gateshead-----This George now ! an infant loose ball as the saying goes, then he could have been brought up by and educated, trade traing with Gibson's and if John Hood did remarry by 1794 to raise another family, George Hood would not be part of it as tied to his now established school/trade education started before John Hood remarried.
