According to Gundrun's SimDNA in SimPE she had brown hair before it turned grey. Although she has brown eyes in her thumbnail, her genetics are for grey eyes. The reason for this is because she has a corrupted face. Gundrun also bears a faint resemblance to Violene Sutter, a former resident of Riverblossom Hills. She and her family might have Swedish roots. According to her age data in SimPE, she had 32 days left in the elder stage when she died.
