I am part of the huge Michigan family. If your Augusta is the daughter of Michael and Elizabeth Hohenstein Drewnoski then I can help. Her siblings are?: Michael/Carl/August/Christian/Laura/Louisa/Gotliebe/William and Marie and Augusta! 10 children. Most of them came thru the port of Baltimore in Maryland. Christian and Laura did not come and we are not sure if the father Michael ever made it. her birth year would be very possible as well as immagration year. I have found that they came singally or twos and with family friends. look forward to hearing from you. LInda
