By the late 19th century, the children are identified individually, but a caveat: the ages and even sexes of the children may not be correct.
I would add to that caveat that even the child's name might be wrong. An example: My Uncle Jack, whose legal name on the U.S. was Jacob and whose name on his Paris birth record is Jacques, immigrated from France to New York with my grandmother in 1912, when he was about 9 months old. The ship manifest lists him as Antoine, although no one in the family, including his children, has ever heard that name.
