Here is the place to list text which clarify the geographical origin for sets of QUB-files.

• An English chronology 434 BC - AD 315 mentioned by English Heritage: Dendrochronology: Guidelines on producing and interpreting dendrochronological dates (2004) (but by almost no others).

Alchester

• "There is a key dendrochronological date from a gatepost timber at Alchester which demonstrates that this structure was probably built in AD 44 (Sauer 2001, 72) and thus provides not only the earliest secure independent dating for a military feature anywhere in Roman Britain but also a key starting point for understanding the Roman conquest of the region and the early development of the complex sequence at Alchester itself." http://www.buckscc.gov.uk/assets/content/bcc/docs/archaeology/A_ST_Oxford_5_solent_thames_roman_oxon_jan_08.pdf p.4

Northern Ireland

• Ballinderry, the samples in the range Q9846-Q9895, are oak samples, just south of Portmore Lough to the East of Lough Neagh. These may also need to be treated with some caution because they lie in the Lough Neagh plain and may well have been affected by changes in lake level, i.e. their growth response may be different in some way. 54°33′N 6°17′W
• Dorsey, 54°6′48″N 6°32′43″W, Declan Hurl, Cormac McSparron and Peter Moore: Data Structure Report: Dorsey, Dorsy, Co. Armagh, CAF DSR 004 (general arch., no dendroch. details)
• Navan, Navan (Fort) and Dorsey are supposed to overlap in the 6th-1st centuries BC, running from 575-95BC (Baillie & Brown, 'Dendrochronology of Irish Bog Trackways', pp.395-402 in B. Raftery (ed), Trackway Excavations in the Mountdillon Bogs, Co. Longford, 1985-1991 (Irish Archaeological Wetland Unit Transactions Vol.3, 1996), fig.504). See also Wikipedia (English) article about Navan_fort,
• Lisbarnet cottage, about 10 miles South East of Belfast. The oaks are bog oaks that had been dug up in the 18th or 19th century and used as roof timbers in a cottage. Quite a common thing in the area, where poor families were concerned. 54°30′N 5°43′W

"BELIM"

The "BELIM" masterchronology AD 1001-1970 is described (containing also data for the Master Chronology) in Michael G. L. Baillie: The Belfast Oak Chronology to AD 1001, Tree-Ring Bulletin, vol. 37, 1977 (Geocoord data approximately according to map in the article). It is also available among the East Anglia Incident chronology files. The younger part of this chronology, however, was described in Baillie: A Recently Developed Irish Tree-ring Chronology, Tree-Ring Bulletin, vol. 33, 1973. pp. 15-28.

Problems

• No Irish oaks found during 95-13 BC!: Baillie 1995 p. 56
• No English oaks AD 316-403! For the historic period there is now a continuous sequence that runs from the present back to AD 404, and another from Roman contexts covering 434 BC – AD 315. The latter is still reliant on cross-links with Ireland and Germany for its dating since no English tree-ring sequence has been found that spans the fourth century AD.
