John de la Feld - Place of birth; and, date of death questions.

This profile lists John de la Feld's year of death as 1092...
Did John's father, Sir Hubertus, return to France from England? Have seen other family tree that show John's birth as around 1070, and listing Colmar as his birthplace; and, 1120 as the year of his death in Lancaster, Lancashire. Can you refer me to any documentation that I can research. Thank you.
