I think found the translation on Nohime's homyo (deceased Buddhist name).
Okada Masahito's Oda Nobunaga Soogyoo Jiten, pp.161-2. Hopefully the translation is correct. If not please let me know. It goes something like this:
Toady is the day Onabe no kata passed away. June 25th, 1612. My God bless her soul.
Tenka no tame!
