The townland where James Lone was living when he married was Gortgarn, near Cranfield. Sarah worked nearby in Garriffgeery:

This is probably Sarah with her father in Aughrim, Co Londonderry in 1901:

This is probably Sarah’s birth in 1882:

Sarah’s mother’s death:

I can see births for the following children to James & Sarah:
Mary Jane on 27.5.1912 in Derrygown
Robert James 25.1.1914 in Derryhollagh
Margaret Law 12.9.1916 in Craigmore.
These locations are all just outside Randalstown. Labourers often moved about a bit to follow the available work.
Can’t find James in the 1901 or 1911 censuses. Can’t find a birth for him either. Not sure of his origins.
