It is not the same Minton Connell, but there is a Minton Sampson Connell in my tree (1848-1892), son of William Connell and Ellen Sadleir who immigrated from Co. Cork to London around 1845 and had 11 children. Minton married Mary Scott and was a hospital superintendent. He and his wife seem to have had no children and died in the area. My tree is at Rootsweb Worldconnect.
