1641: Swedes and Finns spreading north from Fort Christina (present-day Wlimington, Delaware) first settle in Finland (Chamassungh), now Trainer, Pennsylvania[8][9][10] and Upland (Meckopenacka), now Chester, Pennsylvania.[11][12][13] The New Sweden Genealogy Colony continues to expand northward with new settlements as far as Philadelphia in the following years.
