Not sure if this is of any use but I  thought I'd post this.......   1900 Census Patrick McArdle and family are living on what looks like Boerman Place....running off Atlantic Avenue? Brooklyn Ward 3 District 21.   1910 Census Patrick with family on Nelson Street Brooklyn Ward 12 District 251   I may have confused matters earlier.......... 1st wife is in the 1900 census ( Anna)   2nd wife is there in 1910 census (Margaret)   I gave the censuses of 1900-1930 where I had the family....not what might have appeared as the time scale of my searches for marriages.   Apologies.   Slán, Kevin.
