MARRIAGE OF MISS A. E. L. WILKINSON AND MR. O. B. SHELSWELL.

The picturesque village of Stainton-in-Cleveland Yorkshire, was en fete on the 1st inst., the occasion being the marriage of Mr. Oscar Berridge Shelswell L.R.C.P. (Lond.), M.R.C.S. (England), of Mitcham, Surrey, to Miss Annie Elizabeth Lucy Wilkinson, second daughter of the Rev. T. H. Wilkinson, Vicar of the parish, and until recently Vicar of Ratley, Banbury. The ceremony was performed by the bride’s father, assisted by her brothers, the Rev H A Wilkinson, B.A., and the Rev. C. T. B. Wilkinson B.A.

The service was fully choral. The bride who was given away by her eldest brother, Mr. C. J. Wilkinson, M.R.C.S., of Bolton, was attired in a dress of rich ivory corded silk trimmed with lace and natural orange blossoms, coronet of the same, and long tulle veil secured by pearl pins. Her bouquet, the gift the bridegroom, was composed of white lilac and lilies of the valley.

She was attended by four bridesmaids Miss Agnes Wilkinson (sister of the bride), Miss Augusta Berridge (cousin of the bridegroom), Miss Emily Rayner, and Miss Mary Hobson, who wore costumes of maize crepon, with fichus of white chiffon, fancy Leg-horn hats trimmed with white chiffon and Marguerites. The bridegroom presented each with a dainty pearl and diamond spray brooch, and they carried bouquets of Marguerites and lillies of the valley.

Mr. Burton Luxmore, of London, acted as best man. The bride’s mother was attired in myrtle green silk trimmed with blue and silver brocade, handsome white China silk shawl, and lace bonnet to match.

The path by which the bridal procession returned to the vicarage was spanned by floral arches, and strewn with flowers by the school children, the return of the party being greeted with a feu de joie in the vicarage grounds.

Later in the afternoon the newly-wedded couple left en route for the Continent. The bride’s travelling dress was of fawn corduroy, trimmed with jewelled passementerie.

In the evening to celebrate the happy event, the school children, Sunday School teachers, and members of the Girl’s Friendly Society were entertained to tea in the vicarage garden, after which an adjournment was made to a field, kindly lent by Mr, John Jackson, where various sports and races were indulged in. Prizes were subsequently distributed by Mrs. Wilkinson, and the proceedings were brought to conclusion by dance in the village school-room. The wedding presents were numerous and valuable.
