I looked back through the Chadwell book but found no Albert Louis Chadwell. However, researchers have said that the American Chadwells originate from the same family. The Chadwells came to America from the Cotswald area of England. During the late Middle Ages, many Chadwell ancestors were profitable farmers and engaged in sheep farming. This provided the foundation for the woolen industry that developed in London and areas of the main land.
Genealogy work on the Chadwell family is ongoing in spite of the two published books about the Chadwells. In time I believe your Albert Louis Chadwell will be connected with the others. Best wishes for success in your research.
