In the 1900 census, Heinrich Dohn (1838) & Catharina Hofmann Dohn (1836) were living in New Jersey. Their daughter Catherina Dohn (1866) was married to George Geair and had two children, William (1892) & Catherina (1899). The census had the spelling Done and Geer.

Heinrich and Catharina Dohn died in 1905 & 1908 so they do not appear again in any census.

I checked the 1910, 1920 & 1930 census and found that George and Catherina Geair had more children so their children were William( 1892), Catherina(1899), Marie (1902), George (1905) and Alfred (1912)
