“There is no doubt as to the origin of the fame given to the pioneer town- ship division; very many of the Ulsterites who settled in Lancaster County were from County Donegal, in Ireland. The influence of the Scotch-Irish is also seen in the naming of Derry, after Londonderry. Derry was one of the township divisions decided upon when Lancaster County was organized, but when Dauphin County was organized Derry Township could no longer be claimed by Lancaster. Rapho can also be traced without reasonable doubt, for the town of Rapho is the ecclesiastical centre of County Donegal. ‘The Roman Catholic bishop of Raphoe is practically Bishop of Donegal; and the Episcopal Bishop of Raphoe has jurisdiction in Derry.’ The derivative of Mount Joy, however, is not so easily determined. Dr. Dubbs suggested, though not seriously, a French origin, 'Mont-Joie' being an ancient battle-cry of the Franks. There is not much evidence to support such a suggestion, even though the first white settlers in the Donegals were the French-Canadian Indian traders. Mount Joy may safely be associated with dramatic incidents of British history; either the breaking of the boom by the vessel 'Mountjoy' and the consequent raising of the siege of Londonderry; or the breaking of the power of the Catholics in the North of Ireland by Lord Mountjoy in Queen Elizabeth's last years, making possible King James the First's plan to colonize Ulster with Protestants from Scotland and England. Conoy Township, on the other hand, though seemingly an Irish name, is said to have been derived 'from a tribe of Indians that formerly inhabited the region.'"
"Early Settlers in the Donegal Region -The Indian traders were in the Donegal country many years before the first of the regular settlers came; some were in the region in the seventeenth century. The first permanent settlers in what may be termed the Donegal region located along the Chiques creek, beginning in 1716, and spreading eventually over most of the five town- ships now represented in the original Donegal. The list is not complete, but it at least establishes the time of settlement of some of the principal Scotch-Irish families of the ‘Upper End’ of the county. Robert Middleton is shown as settling in 1716; John and George Stewart in 1717; Peter Allen, Robert and William Buchanan, William Bryan, Thomas Bayly (Bailey), Henry Bealey (Bayley...Bailey).............”
“The Bayly family, the head of which was Thomas Bayly, settled about a mile west from Mount Joy borough, on the turnpike. He died in 1734. His son John has been already mentioned herein. His son James bought the farm later owned by the Cassel family, in 1761-62.David Cassel was the founder of the village of Sporting Hill, on the road from Manheim to Mount Joy.John Bayly was a wagon master during the Revolution, and much concerned at the attitude of the 'Dutch' in his vicinity. He was justice of the peace, and once reported to 'His Excellency Thomas Warton, Commander and Chief in and over the State of Pennsylvania,' that 'the opposition given to the laws by the Dutch at length hath Broken out into open Rebellion, they had threatened' so much and bound themselves to each other, that any Constable that would levy on their Goods, for the fines imposed by the Militia law, they would Rebel against them." "The outcome was that resistance to the officers of the law brought a volley from the latter, and so much other trouble that justice Bayly reported that the Donegal militia, though under marching orders, were held 'till we suppress this Rebellion.' He wrote: 'These three that are Shott are of these Conscientious People menoneasts who pretend non resistance and persive Obedience, and there is about 15 or 20 more of the same sact in the publick Cabal.' John Bayly died in 1793 or 1794. Part of the Bayly estate was sold to Thomas Anderson in 1763, but it later was acquired at sheriff's sale by James Bayly."
