Searching for WITTIG families that may be related to my GGrandfather, Johann WITTIG, b 24 June 1810 in Saxony, Germany and my GGrandmother, Marianna PRESCHER, b June 1815 in Seidendorf, Saxony, Germany. With their two children, Josef and Ferdinand who was my Grandfather, they came to America ~ 1850? and settled in Milwaukee, WI, USA. Assume they both had brothers and sisters who may not have left. Thank you.
