Ork 1680 3

The map of Orkney by Kitchin published in 1749 shows no links to the Collins survey as assessed from its errors but appears to be derived from that of Keulen (with an error correlation of 93% (Table 5) . In this case, comparison of place names is inappropriate because many of those by Keulen have been affected by its Dutch origin. Solely on the basis of similarity of spelling, it appears that Kitchin may have used Moll as a major source of “anglicized” names.

The positional errors in the map by Bellin were not strongly correlated with any of the other maps but there was a suggestion that the place names had been influenced by the 1749 map by Kitchin.

The map by Kitchin and Barber published in the “Gentleman’s Magazine in 1778 shows no evidence of a link in its outline nor in its place names with either the earlier 1749 map by Kitchin or with that published in 1750 by Mackenzie However, the portrayal of Orkney in the subsequent map by Conder of the north of Scotland shows clear links to the Kitchin-Barber map with an error correlation of 82% and a place name correspondence of 65 percent (Table 5 & Table 6). It seems likely that they were both derived from a common source which has yet to be identified. Unusually the Kitchin, Barber and Conder maps show longitudes based on Edinburgh.
