Reverend Lucius Smith married Frances Miller Seward and William Henry Seward. He comes up in Frances Miller Seward's 1837 letter of August 19 to Lazette Miller Worden, and was present in Mayville, NY at time letter was written. Context: "Last Monday we took a lumber wagon and went on an exploring expedition intending to return Tuesday evening to be in readiness to meet the Bishop"; "but it was Tuesday night, we expected by nine oclock the next morning the Bishop Parson Smith & wife and Mr & Mrs Peacock with as many episcopal brethren as they chose to bring along to dinner"; "Parson Smith, wife, and daughter had all been here, robed themselves and gone to church at ½ past 10"; "Parson Smith & wife came back to tea. 3 young men also & Collins' singers and musicians. Parson Smith wife and daughter went home soon after tea feeling very jolly – the Bishop left in [the] evening boat for Buffalo"

There is also a website source mentioning Parson Smith's relationship with the Seward family: "In a 24 July 1836 letter from Seward in Westfield NY to his wife Frances at their home in Auburn NY, Seward described his initial arrival in western New York. “We landed in the rain at Dunkirk, at two o’clock on Thursday [21 July].” A half hour carriage ride brought them into Fredonia NY, “a very pretty village,” where the party “took breakfast the next morning with our old friend the Rev. Lucius Smith and his family.” Smith was at that time the rector of Fredonia’s Episcopal Church, and it was at his home that Seward first met his longtime friend Hanson A. Risley ( ) of Fredonia. In editor Willard McKinstry’s “Memorial of Hanson A. Risley,” which appeared in the Fredonia Censor of 6 September 1893, McKinstry said that after their marriage “the young couple went to board at Parson Smith’s. The parson came from Auburn and while there had married Wm. H. Seward to Miss Miller. When Gov. S. came from Auburn to Westfield to take charge of the Land office, he stopped to visit his old friend Parson Smith, and there formed Mr. Risley’s acquaintance, and began a friendship which lasted through life.”
