"The Lagan Vale Estate Brick and Terracotta Works Limited, of which Colonel the Right Hon. R.D.G. Sharman-Crawford, D.L. is chairman, has just paid an interim dividend at the rate of 5 per cent. per annum" in the Northern Whig - Friday 21 January 1921
A reasonable surmise would suggest these streets which were built on the site or close to Lagan Vale Estate Brick and Terracotta Works take their name from the first part of the Sharman-Crawford surname.
"Read letter, dated 15th inst., from the Lagan Vale Estate Brick & Terra Cotta Works, Ltd., renewing their application for the approval of proposed names of new streets on their property situate off Stranmillis Road. The Committee having re-considered the matter, it was resolved – That the names submitted be approved, viz., Sharman Road, Lucerne Parade, Prince Edward Park, Geneva Gardens, and Penge Gardens". (16th June 1925)
