HI I am a Mangas relative Eli's brother Casper, his son George A. Mangas. ANyway I have been looking around on ancestry.com for you. I found the 1930 census for Augustus and his wife Lorette or Loretta It shows both Pauline and Irene to be 19 years old (twins: but they were born in 1910 which would have been after Carrie A. Mangas died. Another sister listed is Bernice 12 years old. The boys you mentioned are not listed in this census. Augustus is 66 years old and wife is about 43. If you don't have this census I can transcribe it better for you. Let me know. Lindsey
