Going into private medical practice in County Londonderry, Morrison was also involved in Unionist politics there.[4] He lived at Aghadowey.[5] He later became coroner for Coleraine.[3] A Presbyterian, he was active in General Assembly meetings, and also took part in medical societies as a reformer.[4] When Denis Henry, a Catholic, stood for the South Londonderry constituency in the Westminster parliament, Morrison endorsed him.[6]
Morrison married in 1884 Louisa Jane Whitley, only daughter of the late David Whitley of Ballymena.[2] They were both buried in the graveyard at Aghadowey parish church, as were two sons.[10]
