Looks Templar related to me as well.
Erik Jedvardsson (later St Erik) lived 1120 - 1160, king between 1150-1160 is thought to have organised a crusade in the East ie Finland and the Baltics of today. His father Jedvard Knutsson Bonde took part in a crusade to Jerusalem. Templar? However, putting gifts in the graves was more a heathen than Christian custom.
