German Sauls to Australia

[Dorothy]

My grandfather J. Martin Saul b. 1866 Rotenburg/Fulda migrated to Victoria Australia 1880, to join his godfather and uncle, J. Martin Saul b. 1830 Rotenburg/Fulda, who had arrived in Victoria 1854. (J is for Johann)
He visited cousins in London on the way to Australia.

Grandfather's father was Hermann Saul b. 1821 m. 1863 Rotenburg/Fulda Christine Hoffsommer . b. 1844 Allendorf/Rotenburg.

Grandfather's cousin Lucy Saul b. 1866, went to America from Germany about 1895 and all contact was lost.

Are there any other Sauls with a connection to Rotenburg/Fulda, or the names Schweinitz, Ulm, Diegal, Schaub, Killmer??

Thanks
Dorothy
