The main ethnic groups in the USA when the Manifest Destiny took place were mainly Native Americans. I don’t know exactly what their tribal names were, but for sure native Americans were the main ethnic group.
The manifest destiny of 1845 impacted them in a bad way bc the settlers basically pushed them out of their homelands. The settlers made war against them and the native Americans with less weapons would lose the battle.
In essence, the Native Americans has their lands stolen from them and their people killed because the settlers believe that they had the God-given right to expand their territory, even if it meant killing off other people.
Pennsylvania was established by William Penn (and was named after him) with the idea that it should be a haven ( a safe place) for the Quakers who were prosecuted elsewhere and they would feel safe in Pennsylvania.
