Robert was asked in another thread: "Does his death certif list his parents names?" He answered No.
The following information was posted by that volunteer, taken from a rootsweb tree:
AUGUST August Braun Birth 05/27/1839 in Germany Death 05/05/1912 in Saint Louis, Minnesota
ANNA (spouse): Anna Rasal Birth 05/10/1854 in Germany Death 1891 in Duluth, Minnesota, USA
HEDWIG Hedwig Pauline Anna "Harriet" Braun Birth 05/02/1889 in St Louis County, Minnesota, USA Death 01/26/1954 in Redmond, Oregon, USA spouse Sydney Denton Pierce 1885-1961
Robert's reply to the above volunteer refers to two more children. He does not give their names, but we can guess Robert is aware of the Richard Frederick Braun you mention.
Robert further says:
Richard George Braun was born 1874 in Steffin, Nordwestmecklenburg, Mecklenburg-Vorpommern, Germany, and so was Elizabeth Welhelmine Braun b.1876 d.1918 was born 1874 in Steffin, Nordwestmecklenburg, Mecklenburg-Vorpommern, Germany
Not clear in his post who those two people are.
Yes, you would need Robert to show up in order to continue.
