Hi there.I've just read your message to Keith asking about John Alder marrying Sarah Jackson (nee McFadyean)... Well, the story is...is that Sarah (my gggrandmother) was married to Alfred Jackson of Darlington, I don't know when she married him.It's told that 'she' divorced him, which would be quite strange in those days, but this is how the story goes. She then moved to Middlesbrough and became the housekeeper of John Alder, aka Jack.I don't know if John was still married to his first wife at the time.The next thing is that Sarah and John had apparently gotten married, however I can't find anything anywhere stating that they actually got married. ( I believe that they never did get married and Sarah just changed her name to make it look right. Sarah and John had two children, Connie and John (aka Jack). It says on thier birth certificates that her name is Alder, formerly McFadyean. Sarah's 'partner'/'husband' John was an Engineman at the Ironworks and he died in 1918, when Connie was only 12, as Connie finished school straight away in order for her to go to work and bring some money into the house.John was apparently crushed between two train buffers, which is what killed him.
I hope that this info is of some interest to you and that it answers some questions for you.
