The son was Thomas Richardson Walker who was married to Annie Walls of Yulethorpe (Youlthorpe?).
The daughters were Mary Emma Walker, who married James Floyd Tennyson in 1871 and Annie Walker, who married William Lascelles Cowburn before they left England. Annie and William Cowburn lived in Winestead and at the railway station at Patrington before emigrating.
From notes left by Francis Walker, my wife's grandfather and the son of Thomas Richardson Walker's brother William, we believe that the Tennyson's produced Arthur Ake (see picture below - taken from a newspaper cutting), Mary Evelyn and Harold.
Arthur Ake Tennyson, died 1950, aged 76, Alhambra
The Cowburn's produced Raymond H., Edith Annie and Alice May.
Thomas and Annie had four children, Thomas, Arthur, Edith and Annie, before they left England in 1881. Unfortunately Annie (Walls) died that year. Thomas later married Mary Rosenauer and had 14 children with her, Martha, Clara, John, Raymond, Herbert, Francis, James, Josie, Sophie, Carl, Mary, Margaret, Alice and Henry. We have no information on these 14 Walkers. However, we do know that of the first 4 children born to Thomas and Annie:
Harold Tennyson then married Edith Annie Cowburn, his cousin. We believe that Arthur Tennyson married Florence West, who had been born in Beverley, Yorkshire. Mary Evelyn Tennyson married O.M. Caulk, Raymond Cowburn, who had come from Patrington, married Florence M. Poulton and Alice Cowburn married E.H. Brambley.
Raymond Cowburn and Florence M. Poulton had a son Louis E.(born 1914) who married Bertram Carmen and had a daughter Carolie (born 1941)
Harold Tennyson and Edith Annie Cowburn had Mildred Loise (born 1910) and Lois Evelyn(?) (born 1913). Mildred is believed to have married Arnold B. Nelson of Modesto, California and a daughter Janet and a son Richard Douglas Nelson (born 1941). Richard is understood to have two sons, Steven (born 1963) and Michael and a daughter Sherrie.
Arthur Tennyson had two sons, James and George and a daughter Jane. James Tennyson had a son, also called James, who in turn had four children (Dianna, Susan, Mike and Claudia. George is believed to have had a son called John Goodson (b 1944).
The newspaper cuttings we have for Arthur Tennyson state:
