Translation of "decease" into Persian

One morning, about ten days after Mrs. Churchill's decease

تقریباً ده روز بعد از مرگ خانم چرچیل،

I am texting you three names, all recently deceased.

دارم برات با اسمس سه تا اسم ميفرستم. که هر سه تازگي مردن

During the 19th century, it was customary to photograph the deceased before burial.

در قرن نوزده ام. رايج بوده که از اشخاص فوت شده قبل از تدفين عکس بگيرن
