Family photo, don't know what this means. Little boy is middle left. I speculate it could either be a religious thing or a funeral thing. To give some context, this is a Polish-American family living in New England.

Thanks in advance.

Black suit, white carnation lapel, and white ribbon around the left arm was the standard uniform for Polish boys undergoing the Catholic rite of Confirmation.
