Hi Duane,
Francis Sheehy Skeffington was christened Joseph Christopher and was known as Joe by most of his family. He was called Frank when he went to university. His father was Dr Joseph Bartholemew and his mother was Rose Magorian. JB came from Co Down as did Rose. JB was a schools inspector and was posted all over ireland, hence FSS being born in Cavan. JB's father was either george Lindsay Skeffington (JB is buried in Downpatrick cathedral in the same enclosure as george lindsay) or Joseph skeffington (father's name given on JB's marriage licence). I favour George Lindsay. In which case his mother was Mary Murphy.
JB had two sisters-Isabell -a school techer and Justina, who ran the family shop. (information from letters from Bella to FSS)
Hope this is helpful
