Hiya,
I see you have on your tree that Annie died 1901
1901/C2621 Annie Alice Wilson John McCarthy Christina Amelia Wilkins
Did John remarry?
There is more than one John WILSON that died in Jan 1943 and I am trying to work out which one is yours.
The easiest way to find him and be certain you have the correct John WILSON death would be to purchase the death cert...other than that knowing who he may be buried with would help.
