Leif Halfdanarson

Leif Halfdanarson is the long deceased grandfather of Erin Singles and Loki Beaker, and the father of Gundrun Beaker, and husband of Ingibjorg Halfdanarson. It is most likely he was named after Lief Erikkson, Norse explorer.

Strangely, Lief and his wife didn't seem to pass down their brown eyes to their grandchildren. Erin has green eyes, and Loki has blue. Loki's brow is different, too.
