Besides my father, whose loss has become a public matter, my dear and faithful wife, in whom I had hopes, my self-sacrificing sister who dedicated herself to serving her parents and finally received her reward, along with her young child, and my other sister’s husband, who was a knowledgeable and noble person, joined the caravan of martyrs.

Do not neglect to help and assist one another.
