Can anybody help with information on Percy Lionel Collingwood and his wife Constance Mary.

They married 8/11/1911 - Not sure where on the IOM and their last known address was Woodgate,Beaumont Rd Ramsay. The name of their house was changed to Thurot by new owners. Sorry no dates. Info provided by their cousins in USA. Can anybody help with death dates and if they had any children.
