Hi Dale,
I'm not sure how much help I will be, but I'm willing to give you the tips I learned researching my Quaker ancestors!
The good thing about Quakers is that they kept good records.
If you go to Search and use the card catolog, on the left is the Title and Keyword search, under Keyword type Quaker and all the records dealing with the Quakers will come up.
I did not see one for Indiana, but there are a couple for Penn. From there just search the titles for the names you are looking for.
It is helpful to find a list of the abv. that they used. A couple different threads on this board are helpful, or just google Quaker abv., you can also get a list at the begining of most of the records.
I did a quick search under the Penn records and both of your sirnames came up.
Good Luck,
Kristine
