She married William Conolly in 1694, a speaker of the Irish house of commons and purported to be the wealthiest man in Ireland.

[1] Upon the death of her husband in 1729, Connolly inherited estates in Wales, as well as in counties Meath, Roscommon, Westmeath and Kildare.

Living on Capel Street, Dublin and at Castletown House, County Kildare, she entertained a large circle of friends.

She commissioned a monument in her husband's memory by Thomas Carter, in Kildrought church, Celbridge.

Her table was open to all her friends of all ranks and her purse to the poor ... she was clever at business, and wrote all her own letters ... she was a plain and vulgar woman in her manner but had very valuable qualities.
