I do have information on this. William Aldrich's father was also named William Aldrich, born in Norwich as well, born in 1532. His father was Gregory Aldrich, unknown date of birth. Gregory's father was Thomas Aldrich, born in 1473 in Norwich. This is as far back as I have been able to find. I do plan on taking a trip to England in the next year or so and examining the public records available. I am highly interested in finding out the Aldrich ethnicity, be it Anglo-Saxon, Norman, Cornish, Viking, Celtic, Pict, etc. I know record keeping past the 1200's is scarce because they did not keep records as a standard practice, but I would like to do all I can to find more information.
