Annie Elizabeth Switzer

[Jimmy M]

Hi

I was wondering if any kind person could provide some information on Elizabeth Switzer who was a daughter of John and Margaret (nee Henderson) m1837 – John was the son of Nathaniel and Ann (nee Teskey) Switzer – of New Park, Co Tipperary.
Annie E married William Alexander Playfair in 1869 and they had 6 children, all born at Ballybrack, Glenville, Co Cork. After William A died in 1878/9 she married a Captain Donald Henderson in Glasgow, which is a long way from Glenville! The information I am seeking is

1/ Annie E date of birth

2/ As both her mother and second husband were ‘Hendersons’ does anyone know of a family connection?

3/ Anyone any knowledge of William P's earlier life as  I have hit the ‘brick wall’ in this line of  research.
