I am searching for the family of my g.grandmother, Margaret Agnew. She was b. abt. 1829, married Alexander Lockhart in Belfast in 1858, d. 1887-Belfast. Father's name on M. cert., shopkeeper. Her husband's will referred to a sister-in-law, Jane Ann Graham (he had no siblings). Researcher hasn't located b. or bap. certificates (family Church of Ireland). Margaret and Alexander had 8 children. Alexander co-founded current Crawford & Lockhart law firm in Belfast. They lived at 1 Fitzroy Ter. Belfast. Any leads much appreciated.
