I know Margaret Hyland Dalton had at least 2 siblings. She had a sister Bridget Hyland who married Anthony O' Malley and they are buried in the O'Malley family cemetery in Blooming Rose, MO. She also had a brother Michael Hyland, who is my Great Grandfather, and he married Margaret Loo and they are buried in St. Patrick's Catholic Cemetery which is located in a very small Irish community called Tipton, IL, not far from St. Louis. Michael died very young, when my Grandmother Katherine Hyland Millmann was still a baby. We have a very old portrait of Michael Hyland and also an old photo of the two Margaret Hyland's together, Michael's wife Margaret Loo Hyland and Margaret Hyland Dalton. I look forward to hearing from you.
