Work has been getting in the way of my personal projects again, but yesterday at an extended family lunch (and in fact the adjective can be applied to both nouns) I met and photographed my wife's brother's wife's sister's daughter for the first time, and as such she qualifies to be included in my 500 portraits project.  There's probably an iPhone app to let me find out the proper term for our connection but if there is I don't think I need it right now.
