Churchrecords irish geneaology show Susan Charlotte Magrath was born at 78 Capel St to parents Robert Charles & Cecilia (26.9.1864)- despite what it says on peerage.com. Her address on marriage to Christopher St George French in Dublin is given as 16 Glengariffe Parade - the home of 'parents' recorded at that time as being William & Elizabeth. When Susan Charlotte was born William & Elizabeth lived at 72 Capel St (3 doors away). William & Elizabeth did actually have a child Susan/Susanna (b8.2.1862). William was my great-grandfather. Susanna's niece told me that Susanna herself married in Australia.
