I knew that Isaac Johnson of Chatham, Connecticut had a Revolutionary War Pension File, and I knew that his wife's maiden name was Rebecca Cole.
Here is the Footnote.com new home page - it has a search box at the top just waiting for a name to be put in:
I resisted the urge to put the name in the box, since I knew that doing that would give me too many matches and I'd have to select the Revolutionary War Pension File collection anyway. Instead, I scrolled down a bit to the "Search by Historical Era" row and rolled my mouse over "Revolution - 1700s-1815" and the list of collections for that era were visible:
I clicked on Revolutionary War Pensions from the list, and this screen appeared:
I input [isaac johnson connecticut] in the Search box (see above) and clicked on "Search":
There were 428 matches found for my search criteria, which is too many to look at one at a time. I need to narrow my search. I tried inputting "Chatham" as a keyword and got zero matches. I backed up one screen, and decided to input "Cole" - Isaac's wife's maiden name, in the Keyword box, as shown below:
I was rewarded with only 8 matches (two screens below, they overlap a bit):
The second and third matches have Isaac Johnson and Rebecca (or Rebekah) Cole listed in an Isaac Johnson pension file, so I clicked on the "View Image" button and Page 18 of the Isaac Johnson pension file appeared:
The search process described above seemed very cumbersome to me. The Search process seems to take a really long time compared to other genealogy database search engines, even when you start from a specific database as I did in this case. If I didn't know to narrow the search using a state (included in my first search term) and then the wife's maiden name (it was lucky I knew that), then I would have taken several hours to try to find the right Isaac Johnson in the 428 matches resulting from the initial search.
