It is odd how far apart in age Emilie's children Richard and Paul are from each other. Are you sure about their birthdates?
Paul Kornfeld was most definitely born in 1889, not 1899. Just fixed the date.
Richard was born 1883 Margreth (Grete) 1884 Maria 1886 Richard 1889
Have I written one of them wrong, as 6 year gap seems OK
Sorry, about my typing error. Well-spotted.
