I have seen her name a couple of ways. Her first nameshows up in various places as Giovanna or Joanna or Jennie. I'm sure all are correct as they are all derivatives or translations. The last name has been shown as Trunco and as Truance. I don't know which one to believe as they could be variations on the same spelling or simply a change in transcription when one person's handwriting looked different to someone else. My records show that she was born in 1882 in Italy and died in 1942 in Detroit, MI. I hope this helps and I'm glad to see you're still in the hunt.
