thanks sonas,my gt gr father's name was denis/daniel crowley.he'not on the 1901 census for dublin or monaghan.he appears on the dublin 1911 census in ash st,aged 21, stating that he comes from monaghan.i have searched monaghan,no joy.i have his marriage cert,he states that his father's name was denis'deceased,both parents deceased. we are told that he came from cork. there is a denis crowley in castle st dunmanway in 1901 aged 11,orphaned with an older brother john.both parents are deceased,i found them.this denis from castle st father's name was also denis, then he is absent from dunmanway in 1911. coincidence,same name,same age,same father's name,both parents deceased,missing from dunmanway census,turns up on dublin 1911 census. i'm trying to find out if castle st denis left dunmanway between 1901 and 1911 ,he's the main suspect at the minute. many thanks sonas. ,
