Friedrich Wilhelm Groth's children were (1) Albertine and (2) Karl Ludwig.My records have them both born the same day, April 16, 1909, in Marburg. Albertine was married January 28, 1928, to Eugen Azzola, reported to be from Romania (born May 13, 1898).They had 4 children, Elemore (1929-?), Friedrich Karl (1931-?), Chrisla (1935-196X)and Axel (1937-?). Karl Ludwig was married January 15, 1936, to Anneliese Bussas, and apparently died in 1940 (WW II?).They had one child, Gisela (1941-?). Doesn't look like this is your "Grote", but offered just in case.
