Tachibana (Mandarin Flower Crest)

Both the Tanaka and Nakamura clans used the Tachibana family crest. The ease of using the crest interchangibly reinforces the probability of ancestors changing the family name from Tanaka to Nakamura.

Surprisingly, our maternal grandmother's family - the Morifuji clan - also uses the same Tachibana crest. The implications are yet unknown.
