I am looking for a Joseph Weir. His daughter Martha/Matty bc 1834 m'd Joseph Black in Malone Presbyterian church in 1858. They were both living in an area called Glenmore,Belfast, at the time of their marriage.Her father Joseph Weir, would have been bc 1795/1800 m'd c 1830.I don't know his wifes name
Martha Weir had at least one brother - John Weir b 1835.( living with Joseph Black and Martha on 1901 census,at Lambeg Co Antrim) Possibly one called Joseph bc 1840,but I can't prove that. Does your research on Weirs go back to 1795/1800 ?
