Sir John Dongan, 2nd Baronet

Sir John Dongan, 2nd Baronet (1603–1650) was a member of the Irish Parliament.

Early life
Dongan was born into an old Gaelic Norman (Irish Catholic) family in Castletown Kildrought (now Celbridge), County Kildare, in the Kingdom of Ireland. He was the son of Jane Rochfort and Walter Dongan (died 1626), who was created 1st Dongan Baronet, of Castletown in the County of Kildare, in the Baronetage of Ireland in 1623.

His maternal grandparents were Robert Rochfort of Kilbryde, County Meath and Elinor Dillon (a daughter of Sir Lucas Dillon, Chief Baron of the Exchequer of Ireland). His paternal grandparents were Margaret ( Forster) Dongan and John Dongan, originally of Fishamble Street, Dublin, a civil servant in the Irish Government who became wealthy and acquired substantial estates in County Kildare.
