Doc group and pictures

[PaulChep]

I have been posting pictures of a document group that I have for two brothers in IR144. With the group came several pictures. Only two of them have any writing on the back. Several of the pictures have the same person in them. I am guess that the brothers Wilhelm and Gottlieb Porsch are in the pictures. I am posting the front and back of the pictures and any help with the translation is greatly appreciated. Mainly I would like to know if the writting on the back identifies any of the people in the pictures. Thanks in advance.
