I came across this interesting article in an 1890's old periodical which I found interesting which tells what happened to the many old graveyards of Birmingham:-
There are many less pleasant places on a nice summer's day, in the neighbourhood of Birmingham, than the Borough Cemetery at Witton. It is rather a gruesome subject to touch upon, but it is none the less a fact, that previous to 1859, when the Witton Cemetery was acquired by the Corporation, the way in which the dead were disposed of in some of our burial grounds, was little short of a scandal. Owing to their over-crowded state, St. Martin's, St Bartholomew's, St. Paul's, and St Mary's Churchyards had all been closed by an Order in Council, made in the previous year, and the only God's Acre left for the borough was at Key Hill and Warstone Lane. By the same order which closed the parish churchyards, the Town Council was constituted a Burial Board, and it was under the powers thus conferred upon them that they bought the land at Witton in 1859. The borough cemetery is 105 acres in extent, and cost £150 per acre. The cemetery is divided into four parts, separate ground being provided for Church of England, Nonconformist, Roman Catholic, and Jewish interments. The total cost of the under-taking, including the laying out of the ground and the building of the chapels, etc, was £46,397. The Jewish portion was sold outright to the community—two acres at £250 an acre, and the ancient people have a separate entrance to the grounds, and themselves defray the whole of the expense of their burial ceremonials. The cemetery contains many remains besides those of people who have died since it’s opening. Corporation and railway improvements have swept away the "Scott's Trust" (Congregational) burial place in Summer Lane, the Cannon Street Baptist Chapel and burying ground, and the Old Meeting House and Cemetery. Seventy-two coffins were taken from the first of these, 142 from the second, and 1,503 from the third, and re-interred in Witton. The ground in which the coffins from the Old Meeting have been deposited is fenced in with chain and granite posts, a handsome obelisk being erected, with an inscription stating the cause of removal; all the cost, £3,639, being defrayed by the Railway Companies, who acquired the old site for the extended New Street Station.
