Starting from the top:
Margaret McDermott (married name) born 1833 Sligo, was widowed and remarried William Gallagher, born 1830 Sligo; a glazier in Carrick on Shannon in 1901.
Margaret's daughter Bridget McDermott, born 1873, had an illegitimate son, Thomas McDermott - born Boyle, Roscommon in 1889, (birth unfortunately not registered).......
Now you've a Thomas, born 1888 in Ck on S!
What FACTS have you that this Thomas from Ck on S is correct??
