Father of Erland Jonsson Hård, born about 1360

[Kevin Casey]

Hej!

Does anyone know of evidence as to whom might be the father of Erland Jonsson Hård (born about 1360, who was himself the father of Jon Erlandsson Hård (Liljesparre))? No suggestions that I've seen have much proof with them. (I've also seen some pretty stories online that mention Erland's wife being Ingegerd Knutsdotter (Bengt Hafridssons ätt), though I believe she was an Abbess and nun, making such a marriage quite an accomplishment!).

Tack,
Kevin
