Girard-Software is the personal website of Serge Girard, bringing together family-history research and practical online reference tools. Its genealogy section features family trees and indexes of surnames including Ahrens, Belle, Berthier, Chaumaison, Courty, Girard, Loiseau, Loriot, Raffiot, Renard, and Wisdom. The site explains the limits of historical genealogical records: information from around 1600 onward is generally more reliable, while earlier dates may be uncertain or unverified. It also notes that many dates recorded between 1600 and 1800 are baptism dates rather than birth dates, and cautions against unsupported claims of ancient or royal ancestry.

Alongside its family-history material, Girard-Software offers a French Republican calendar converter, a Roman numeral converter, and a date calculator. Other listed resources include a clock, Belgian public holidays, a Latin dictionary, and word games. The website invites visitors to support the research through donations and provides links to Serge Girard’s social and genealogy profiles. It presents itself as a personal project, with contact information and acknowledgments for external image and text sources.
