And now you know! Thanks for the swift response, Clancy Docwra people!
Thank you for your email. The second part of the name Docwra, the w is silent. Below is an explanation of how the name materialised :-
Founder Michael Clancy formed M.J.Clancy & Sons Limited in 1958. Originally based in Wembley, the company undertook ground works, drainage and road works in and around London. Over the following fifteen years the business grew and expanded into tunnelling and associated works. A significant development within 1974 was the acquisition of R.E.Docwra Limited, a Public Works Contractor based in North London who operated in the water and gas markets.
April 2001 saw a major restructuring of the business. The original subsidiaries M.J.Clancy, R.E.Docwra, Rees and Westwick were replaced with a single operating company - Clancy Docwra Limited.
Today, the company is still a family business and the joint chairman are Kevin and Dermot Clancy, sons of the late Michael Clancy who originally formed the company back in 1959. The Company R.E. Docwra Limited was owned by a Mr. Docwra.
