The College of Arms search fees are quite steep. To help your research along I have put together two images;

phelps.jpg includes entries in the Grantees of Arms, Burke's General Armory (you can see where some of the entries tie in) and an extract from the 1902 edition of Armorial Families.

phelps-edmund.jpg is taken from the 1881 edition of Burke's Peerage and ties in with one of the entries listed in Grantees. However, there is no blazon given.

Hope that this assists.

Yours aye

Stephen
