Happy International Heraldry Day!
International Heraldry Day was established in 2013 by the International Association of Amateur Heralds (IAAH). The date, June 10, was chosen to commemorate a significant event in heraldic history: on this day in 1128, Geoffrey Plantagenet, Count of Anjou, was knighted by King Henry I of England. During the ceremony, Geoffrey received a blue shield adorned with six golden lions, which is considered one of the earliest known examples of a fully formed coat of arms.
So, celebrate heraldry today!

Happy International Heraldry Day! Thanks for the explanation of the reason for the date chosen.
I’ve just found your blog, and it’s wonderful. Is there something similar to a searchable roll of arms for ecclesiastical heraldry?
Sadly, no.
