I've just had a laugh!

Found Callaghan who died 1877 in a personal family tree on Ancestry. I have found most trees are a mixture of records and guesswork but this takes the cake:

it has a timeline for Callaghan:

1803 Birth Cork, Ireland
1851 arrival in New York USA
1861 census in Camberwell, a hairdresser, unmarried
1871 census in Westminster [not him, but a chap called Timothy McCarthy]
1877 death
1880 Boston, Suffolk, Massachussetts, USA [again Timothy]
1881 West Ham, London [this time a Jeremiah McCarthy]
1891 Llantwit Fadre, Wales [John McCarthy]

and I thought my tree was a muddle!
