Four manuscript survey maps and one plat map depicting areas of
Orange County and attributed to the noted surveyor and judge Richard Egan. One map is dated
1878 and 1879 by Egan. The other maps are undated and unsigned but it is likely that he drew
them during these years. These maps primarily depict subdivisions of non-rancho tracts of
land occupying what is now Orange County, with the addition of some topographical details.
