Hello Liam: Found the marriage record on Ancestry for Thomas Horan and Sarah (Sadie) Burke February 12, 1893. In the column where the certificate requests the names of both parents of the bride and groom, the groom Thomas Horan wrote "Martin and Margaret". So perhaps you might add one more child named Thomas to your ancestry record. Also, a mention by another Ancestry member back in 2001 regarding his great grandfather Joseph who emigrated from Ireland with his brothers Patrick and Thomas Horan in mid to late 1800's caught my eye, as he mentioned that Joseph had been "disowned" because he married a non-Catholic. But the posting was so long ago I didn't follow up.
