The Silver Books for Thomas Rogers, Volume 19, are divided into two parts:
Part 1: This part covers the first five generations. It was originally compiled by Alice Westgate, revised by Ann T Reeves in 2000, and further revised in 2013 by Peggy M. Baker.
Part 2: This part covers the sixth generation, naming the seventh. It follows family numbers 325 to 512 from the Part 1 volume. This part was also compiled by Peggy M. Baker and was published in 2019.

I also see that we need to update our internal link to these books to include the second volume.
