The Pearsall photos are divided into a number of logical groups, but there is overlap with other groups. Some photos of Chet and Roxana's children are in the Pratt gallery, when Roxana took her 3 children to California in 1927 to visit her family, for example.
"Pearsall Family Photos" includes mostly Chet's siblings and parents and relatives.
"Alice's Album" is mostly her young adult photos.
"Roxana's Children" is Mason, Molly and Alice when they were little. The photos in "Chet and Roxana" are not focused on the children.
