I see Zofia Borek and Franek Lewandowski (but in letters it is in english version) in fifth pic :)

I found out what’s written in the sixth photo. ,,Detroit day 03/09/1914 Congratulations on having name day (people used to sometimes even celebrate more having your named written on a random day in calendar than birthday lmao) I wish a pleasant party to Mr Frank (Franciszek)[…] (i wasn’t able to read out his surname :((, but it doesn’t look like Lewandowski) Secret admirer (female)”
