In looking for my family I think I can help you. Robert was the son of Jonas b.1829/30 d.6/2/1894 and Johanna (Sclapp) Mehl b.1829/30 d.7/8/1894. They came to the US in 1857 on the ship "AEQUATOR" They had sons Johann, Robert,and Valentine with them. They settled in Hudson Co NY and had more children. The following are names of children I have found. Johann, Robert,and Valentine,George,Barbara,Margaret, Johanna,Henry,Frank and Rudolph. Your Robert was born 1854/55 in Germany married Katherine Dorthea Schafer daughter of Joseph and Katherine(DeBaerer)Schafer of Alsace-Lorrane France. They had a son Walter b. 11/1/1893. I don't have any info on spose or siblings of Walter. Hope this helps.
