The name is supposed to be of Scandinavian origin and derived from Ingialld. During the ninth century the Scandinavian pirates often descended on the east coast of Great Britain, and in after years, many of this nationality made settlements here, especially in Lincolnshire. These people were a hardy seafaring race owing to the nature of their country, but under changed conditions of environment settled down to tilling the soil.
The earliest record found is that of the will of Henry Ingalls, grandfather of Edmund, and made in 1555, he probably having been born about 1480. The next record is that of Robert the father and made in 1617. An abstract of both wills are given. The name of Ingalls is still common in England.
The etymology of the name is "By the power of Thor."
