Hi Mmorokutti,
I know of at least four Henry Twamleys from Wicklow including Ballymorrage, Cronelea, Coolkenna, Bray and Ardoyne/Tullow. Because most old parish records from Carlow/Carnew were destroyed in the 1798 Rebellion or Dublin fires, if you could provide me with more information, such as siblings' names, birth dates or townlands, I might be able to assist you in finding your Henry and John Twamley. Do you know Anne's maiden name or their children's names or birthdates? I have not come across any British military records for Henry Twamleys; however, Twamley records are typically unrecognizable due to bad misspellings. Your Henry Twamley was likely a farmer.
About the Wicklow Twamleys
The Orangist, Loyalist Twamleys were in Ireland since 1690. They intermarried with other landed, Orangist families (including Chamneys, Humes, James, Hopkins, Barkers and Morton families, just to name a few) and served, as they were expected to serve, in the local militias . Several Wicklow Twamleys had mercantile businesses and homes in Dublin. They leased a few large country estates near the border of County Carlow and Carnew, where they were gentlemen farmers. Several were lifelong British Army soldiers (redcoats) who lived on pensions, after they served in regiments in British Indies, Crimea, Madras, Bengal, and Afghanistan.
Around 1798, the Wicklow Twamleys were found in Hacketstown, where they attended the Orange Leader, Rev. James M'Ghee's church in Clonmore, Hacketstown, County Carlow parish (the original Aghold Prebend) after M'Ghee moved from Armagh to become clerk and later vicar of the prebend of Aghold (earlier spelling of Aghold was Aghowle). M'Ghee was a leader in the Orange Lodge, and was Chaplain of the Coolkenna Orange Lodge.
The Wicklow Twamleys were all related and sprung from Cronelea, adjacent Ballymorroge in Mungacullin/Munahullen/ Monahullen; nearby Coolkenna, and several were found in the Coolmanna, Hacketstown/Tullow/Ardoyne and Kilcommon. Two of Wicklow Twamleys, the Rev. James Twamley and John Twamley of Athy, Ballitore, Kildare, were brothers who attended Trinity University in Dublin.
Common forenames were James, Peter, John, Thomas, Elizabeth, Alice, Henrietta, Richard, George, and Henry.
