[2] Colonial authorities were concerned about the migration of Shawnee and Lenape communities from Pennsylvania to the Ohio River valley, where it was feared that they would become allies of New France.
Secretary James Logan told the Shawnee, Since your nation first left their settlement near Paxtang, on the west side of the Susquehanna, and retired to so great a distance as the River Ohio, or Allegheny, this Government has ever been desirous of a conference with some of your chiefs.
Some of your older men may undoubtedly remember that about forty years ago a considerable number of families of your nation thought it fit to remove from the great river that bears your name,[3] where your principal correspondence was with those of the French nation.A new treaty was concluded at this council, in which it was declared that the Shawnees had moved from their former home on the Susquehanna to the Allegheny.
[4] After a series of violent conflicts between Indians and white settlers, including the Battle of Galudoghson, Meshemethequater, Sassoonan and other chiefs from the Six Nations (including Shikellamy), the Tuscaroras, and the Lenape met with Conrad Weiser and Andrew Montour at the village of Shamokin on 4 February 1743, and received wampum from Weiser, who was trying to persuade the Shawnees not to attack English traders living on the Allegheny, to prevent war from erupting.
He was with his cousin Peter Chartier, Neucheconeh, and about 400 Shawnees on 18 April 1745, when they robbed eight English traders of their goods on the Allegheny River.
[10]Meshemethequater returned to Lower Shawneetown in 1750, and met George Croghan, Andrew Montour, Robert Callander and Christopher Gist there on 30 January 1751,[11] during which he was the chief speaker for the Shawnees and made a warm speech which concluded: "We hope that the Friendship now subsisting between us & our Brothers will last as long as the Sun Shines or the Moon gives light."
