I'm trying to prove or disprove a possible family connection and could use some advice on where to look next. My 3G grandparents were Christian Haas and Anna Eva Weigand who came to Baltimore from Bavaria, along with their children, in several separate groups, in the early 1850s. Among the children were four sons, Martin, Conrad, Franz and Johann Adam. (There were also several daughters.) I have pretty solid information on Martin, Conrad and Franz (who went by Frank in the US). My trouble concerns Johann Adam. I've found a George Haas that I believe is Johann Adam but, I don't know how to prove it. Johann Adam's birth record in Bavaria puts his birthdate as 18 Feb 1843. In 1851, Anna Eva arrived in Baltimore with Franz and Adam. Their ages match their birthdates fairly well. In the 1860 Census, Christian and Anna Eva have two sons living with them, Frank and George. Their ages match those of Franz and Johann Adam. In the 1870 Census, I have a George Houst (age 28, from Sweden(?)), with wife Ricca (age 25, from Bavaria) and children Louisa, Frank and Andrew, living next door to Martin Hesse (from Hanover) & family. I've pretty firmly established that Martin Hesse is actually Martin Haas (from Bavaria, not Hanover), son of Christian and Anna Eva. I have the death certificate for a George Haas, died 15 Sep 1936. He is buried in Mount Carmel Cemetery, in the plot next to Conrad Haas. Buried with him is his wife, Louisa F Haas (1847-1889). According to his death certificate, George's birthdate was 17 Feb 1843, one day off from Johann Adam's and he was born in Germany. The space for his father's name is left blank, while the mother's name is filled in with Louisa Horstmann (her birthplace his given as Germany). His wife's name is given as Louisa. I have information on several of George's children. On all of their DC's, the father is filled in as George Haas and the mother as unknown. Except for one, Henry Haas (1874-1914). Henry's DC has his father as George Haas and his mother as Fredericka unknown. What I'd like to believe is: Johann Adam came to the US with his mother, changed his name to George and, married Louisa Fredericka Horstmann, died in 1936 and was buried in Mount Carmel. Would you consider the above evidence sufficient to draw that conclusion? Or, if not, what would you look for next? Researching: APPEL, BOROWSKI, CERNOHORSKY, DEMBOWCZYK, HAAS, PIETROWIAK, ZARAS
