One of the first of these was undertaken by Anders Johan Sjögren, who brought the Vepsians to general knowledge and elucidated in detail the relatedness of Finnish and Komi. Still more extensive were the field research expeditions made in the 1840s by Matthias Castrén (1813–1852) and Antal Reguly (1819–1858), who
