Tachibana (Mandarin Flower Crest)

Both the Tanaka and Nakamura clans in my line used the Tachibana family crest. This would reinforce the theory of my ancestor changing the family name from Tanaka to Nakamura because of the ease of using the crest interchangibly.

I was even more surprised to learn that my grandmother's family - the Morifuji clan - also uses the same crest.
