They were in Peoria, Peoria County, IL, in 1870, but Herman QUAST was transcribed as Harmon QUEAST, 41, & QUCAST, 47, Prussia, on two indexes.He was probably 41 because there was one Herman who was 30 in 1860.Eliza was 22, b. Prussia, and Annie, 1, IL, in 1870.
Martin K. in Plochingen, Germany, found a family for Johann(es) / John KNOBLAUCH, bpt. Bohmenkirch, Catholic, who applied to emigrate in 1857, whose records match the one in Metamora Twp., Woodford Co., IL (just east of Peoria).
Unfortunately, John's daughter Elizabeth was b. 1845.Could her age have been incorrect in the American records (b. 1847-8)?
Google "Illinois Ancestors Tombstone Project" +Metamora to find details for John (22 May 1814 - Aug. 1897) & Katharina, b. 1815.I couldn't find the family of John KNOBLAUCH in 1860 to see whether an Elizabeth was with them.There was an Elizabeth KNOBLAUCH, 13, in Peoria, 1860, probably a servant, in a LUTHY household, which may have been a boarding house considering the different names listed.
Is anyone researching QUAST or KNOBLAUCH of the Peoria, IL, area?
