I have seen resumes with Personal Information section filled with details such as Name of Spouse, Marital Status, Children, Father's Name, Nationality, and some containing even the Religion. (freesampleresume.in)
This section gives you an opportunity to reveal something interesting, which isn't included in the personal information section. (senior-dating-sites.com)
Students can skip the personal information section and log in by first name only. (educationworld.com)
