I found a map of the Battle of Spotsylvania that shows the location of the Perry House and property on this webpage https://www.history.com/topics/american-civil-war/battle-of-spotsylvania-court-house
Dear Ms. Holloway,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located National Register of Historic Places and National Historic Landmarks Program Records, 2013 - 2017 in the Records of the National Park Service (Record Group 79), which includes the file unit National Register of Historic Places and National Historic Landmarks Program Records: Virginia, 1964 - 2012 that contains the digitized document Virginia SP Spotsylvania Court House Historic District. The application may contain information or references for George Perry and Sunlight House.
In addition, we suggest you review the blog post about Researching the History of your Property.
We hope this is helpful. Best of luck with your research!
