Thank you both very much for the input, there was talk about him and his wife moving to the USA, but it certainly appears she did not.
It appears that Ebbi/Abby went to the USA pre 1875. This does add up as he has been hard to track down.
The name Edward Peoples is totally new! I now have him as Abraham, James, Ebbi, Ebi, Aby, Abbey and Edward! On Samuels birth register in Scotland, his surname is "Peebles", all makes him hard to track down.
They were married presbyterian and appear to have converted.
On the 1901 census, Sarah reports as married and then as widowed in 1911? I wonder if this is the time gap where he died? I had originally thought that the 1901 census was not accurate or she reported married even though he was dead. Very interesting.
As for the Thomas Peoples and Jane Kidd marriage, I found a reference to it on a Scottish thread:
