John Graham 1833 : Short Biography

 John Graham came to America in 1853. I believe he came with his younger brother Christopher who was my great grandfather. Their parents were John Graham and Rosehanna Mullins. John and Rosehanna came to America in 1854 with at least two more sons, Patrick and Joseph. Joseph is listed as being born in Galway in 1852. They are in the 1860 census for Perry Ohio.

My questions  are where did they leave from and where did they arrive? Who were John and Rosehanna's families in Ireland? I am stuck and can't find anything for them. John and Rosehanna remained in Ohio.Christopher was married to a woman named Mary Ann Conway. I know nothing about her. I know they had a son named Christopher and a daughter Rosa. In 1880 census there was no wife listed but Children listed as Daniel and Edward Mcgoldrick along with Christopher and Rosa and a girl named Ellen. A women listed as a servent named Margrett Carey who later became the elder Christopher's wife. Christopher moved his family to Mcpherson Kansas by 1890. His wife Margrett died there. Around 1903 Christopher moved to Oklahoma  with his son Christopher and daugther- in- law Wreatha Free and the frist 4 of their 12 children. He lived with their family at Hinton Oklahoma until his death in 1910. He is buried in the Catholic Cemetery east of Hinton Oklahoma. His son Christopher is also buried there.
