Hello :)
We've corresponded a few times back in 98' regarding the Ogawa of Iyo province. I recently came across a picture of my great-grandmother, Ogawa Tani, daughter of Ogawa Shunzo. I've noticed that she has a mon on her kimono, but I can't quite make it out. I'm having my father's cousin do some research to see if she can find out what it is.
I don't know anything else about our Ogawa lineage except that in our genealogy book, it says that Ogawa Shunzo was a hatamoto of the Iyo Saijo clan. I'm pretty sure that Shunzo was only one of his names, but unfortunately, my ancestors didn't keep a very good record of the female lineage if at all. You mentioned that you have some additional information on the Ogawa family. Would you mind sharing them with me? I would really appreciate it if you could tell me what your wife's kamon is too. Thank you so much :)
