Unfortunately I dont.

Margaret Nixon's father I know his name was James Nixon born in Ireland in 1795, not sure what county and not sure of her mother's name.
From what I have Joseph was born
Nov. 1, 1823 ?, In Ireland.
Margaret was born about 1830 or before.
They had 9 children:
Josiah b.1849, Thomas b.1850, James b.1853, Mary Ann b.1859, Sarah b. 1861, Margaret Matilda b.1863, William Francis b.1865, John b.1869 and Isabella Rowena b.1871.
Joseph's father Thomas was born around 1782 in County Tyrone, Ireland. His death might be July 6, 1869. All I have is a name Betsey for his wife born around 1794, Ireland. However not sure if her information is correct.
And the only child I have from them so far is my great x3 grandfather Joseph however I'm sure there was more.
I've searched and searched, however maybe I'm not doing it right or I don't have access to the records.
Thank you so much for your response.
Amy!
