Looking for James Kavanaugh(various spellings) born in Ireland about 1866. Came to USA about 1880 and married Annie McLaughlin about 1893. The 1910, 1920 and 1930 Washington DC census shows James and Annie living at 5507 5th Street NW Washington DC. James was a DC police officer in 1910 and 1920. He was retired in 1930. According to family stories, James and Annie never had any children. Annie was the sister of my great grandfather, James McLaughlin. Living with James and Annie Kavanaugh was Annie's sister Mary whose married name was Borgis(? spelling). Any help would be appreciated.
