Thomas H. Mullin, Aghadowey (Belfast, 1972) is an outstanding local history. It may be hard to find in the States. Aghadowey was mainly in the Ironmongers Company estate from the Plantation of Londonderry. It was leased to various parties in the 18th century. The Jackson family, who leased the Clothworkers estate as well, held some townlands in Aghadowey Parish on a long-term lease. There is a good collection of their leases to their tenants, rent rolls, etc. at the Public Record Office of Northern Ireland in D/668 (Jackson Papers). The Church of Ireland records for this parish prior to 1870 were among those sent to Dublin and destroyed when the four Courts burned. Records of Aghadowey Presbyterian congregation begin in 1845 and are apparently complete since then. If you check the Public Record Office of Northern Ireland website at _www.proni.gov.uk_ (http://www.proni.gov.uk) there is a geographical index that will tell you what records from Aghadowey Parish can be found in PRONI. You can call up individual townlands on their in-house computers and discover what is available, but I'm not sure that this can be done from the website. All the best, Richard MacMaster
