FInding ownership and financial data
When researching your or any historic home, generally, having the underlying address and ownership data is important. The Montgomery County Treasurer's office (www.mcrealestate.org) is a very important and useful tool to find parcel, sales, ownership, tax, and permit data. Please note that for older properties (pre-1900) the county will use 1900 as a default unless another date has been definitively determined.
If you are having difficult finding the address, particularly those on numbered streets, like W. Third St., you may want to search by parcel ID. You can find the parcel ID, with a free account at www.landgrid.com if you know the location of the property on a map.

Historical Maps
Historical maps can help determine what structures may have originally been on site, and when additions or alterations may have been made. Historical maps also allow tracking street name changes which can help in doing additional historical research.
If you know the name of a resident, you can also search census data for free on www.familysearch.org.
