12627 Maryedwards           Discovered 1971 Mar. 25 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Mary Edwards (c. 1750-1815), of Ludlow, Shropshire, was a skillful mathematical and astronomical computer. From 1773 until her death she performed most of the astronomical computations necessary for the preparation of the Nautical Almanac. The name was suggested by R. H. van Gent.
