Lady Margaret Charteris was the eldest daughter of Richard Butler, 2nd and last Earl of Glengall. She inherited her father’s extensive estate at Cahir, County Tipperary in Ireland, following his death in 1858. In that year she married the Honourable Richard Charteris, second son of the 8th Earl of Wemyss and March. She built Cahir Park as the family home in the locality and in the 1870s owned 16,616 acres in County Tipperary. She was succeeded by her eldest son, Richard Butler Charteris, who continued to live at Cahir until his death in the mid 20th century. In May 1859 an estate of 12,369 acres belonging to Lady Margaret Charteris, Lady Matilda Butler and the trustees of the Glengall Estates in counties Tipperary and Waterford was advertised for sale. In May 1872 almost 1,000 acres in the County Tipperary Barony of Iffa and Offa West was advertised for sale by the trustees of the marriage settlement of Richard and Lady Margaret Charteris. The latter property was sold in January 1873. The purchaser was { mutations.forEach( ( mutation ) => { if ( mutation.type === 'attributes' && visibilityTestDiv.offsetParent !== null ) { debouncedTriggerPostRender(); observer.disconnect(); } }); }); observer.observe( document.body, { attributes: true, childList: false, subtree: true, attributeFilter: [ 'style', 'class' ], }); } else { triggerPostRender(); } } );} );
