I am sure there are lots of Browns out there hitting the same wall in the mid 1800s!
I have a birth certificate for my grandfather in 1869 which give the address as 1 Robert St, district Strand, sub-district Charing Cross.
His parents were Honorah Kelleher and James John Joseph Brown.
I have tried the 51, 61 and 71 census with both names and struck out. Honora'h parents (according to family notes) were Joanna Millar and Jeremiah Kelleher - no luck in the census with them either. I know Honorah was baptized on April 24th 1836 in the church St Mary Assumed into Heaven, and an address of Warwick St. Westminster is also written down, but I don't know if that is the church or the home. Our family seems to have been RC with both Gparent's. I checked the Westminster RC diocese website but couldn't find a church of that name - HELP?!
