Drawing from a framework highlighting how family influence is reflected in organizational identity, we present archival and content analytic adaptations for three key factors signifying alignment between family and organizational identities: family visibility, transgenerational sustainability, and family self-enhancement. We validate these measures using archival data sources, "About Us" pages, and shareholder letters from S&P 500 firms. Random coefficients modeling indicates our measures are largely shaped by temporal and firm, followed by industry, differences. Our work paves the way for further investigation exploring the relationships between family involvement and organizational identity while simultaneously addressing lingering methodological challenges in family business research.
