In the year 1712 another courageous adventurer sought out Conoy. The Swiss Baron Christopher de Graffenreid had been interested in forming a colony of Germans, refugees from the lower Palatinate, at New Bern in North Carolina and also having obtained authority to make a settlement on the Shenandoah in Virginia's remote frontier, he proceeded to explore the neighbourhood. He followed the Potomac up to Conoy Island and drew a map of the surroundings. This map notes the great number of wild fowl on the river, particularly at the mouth of Goose Creek. "There is in winter," he wrote, "such a prodigious number of swans, geese and ducks on this river from Canavest to the Falls that the Indians make a trade of their feathers." Such a description is enough to reduce to envious inanition our Loudoun Nimrod of today whose occasional reward of a few wild ducks may at rare intervals reach the hardly hoped for bagging of a single wild goose, as a rule now far too alert and wary to alight in their spring and fall flights over the county. The wild swan has, alas, wholly disappeared.
De Graffenreid's reference to the vast number of wild fowl on the upper Potomac, in those early days, has abundant confirmation from others. So numerous were the wild geese that the Indians called the river above the falls "Cohongarooton" or Goose River and the English at first gave it the same name; applying the name Potomac to only so much of the stream as lay between the falls and the bay. It was not until well after 1730 that the whole river was generally called by the latter name.
The "Canavest" referred to by de Graffenreid was the village of the Piscataways on Conoy and in his journal he describes it as "a very pleasant and enchanting spot about forty miles above the falls of the Potomac, we found a troop of savages there ... we made an alliance, however with these Indians of Canavest, a very necessary thing in connection with the mines which we hoped to find in that vicinity, as well as on account of the establishment which we had resolved to make in these parts of our small Bernese colony which we were waiting for. After that we visited those beautiful spots of the country, those enchanted islands in the Potomac above the falls." De Graffenreid's "mines" and "establishments" were to be over the Blue Ridge in the nearby Shenandoah Valley; but he shrewdly recognized the advisability of making friends with a tribe so firmly and strategically planted as he found at the settlement on Conoy. As to his "enchanted islands," those contiguous to the Loudoun bank of the Potomac long have had Loudoun owners and seem to its people to be sentimentally part of her domain; as a matter of cold fact and colder law, they lie within the bounds of Maryland; for in 1776 the long dispute over the sovereignty of the Potomac was settled by a clause in Virginia's Constitution of that year relinquishing jurisdiction.
