After much research, it is believed that these paper's belonged to Arthur's grandfather, Frederick Boorom (1838-1921) whose name appears in the first part of the summons below. In 1847 he was 9 years old and thus a minor. The Heath children listed in this section were underage as well.

I have not been able to find the court records for this case. Unfortunately the Hamilton County Courthouse has had several fires in which many records were lost making research there difficult to say the least!

I have not found anyone with additional copies, although they certainly would have been duplicated for each person listed in the subpeona. Thankfully, Frederick Boorom kept these papers, as they have been my greatest resource listing the descendants of Aaron Booram Jr. 

Of those listed, some are children:
Malinda Artles/Ertel, w/o Jacob
Jackson Booram/Boorom
Jonathan Booram/Boorom
Lydia Artles/Ertel w/o Daniel
Mary Rainley/Remley w/o Daniel

At this time, I still have no idea who "Sarah Scott late Sarah Booram" is. She appears to be the same who signed with Lydia Ertel to hire an attorney.

The remaining on the list were Aaron's grandchildren who parent(s) were deceased. These being the children of:
Andrew Booram & wife Sarah Harris
Jesse Booram & wife Jane ???
Elizabeth Booram & husband Joseph Heath
Rebecca Booram & husband William Harris
Amos Booram & wife Catherine Remley

We the undersigned hereby authorize Francis K Butler to supply for us an attorney to prosecute a suit against other heirs of Aaron Boram deceased for the purpose of setting aside said will. Hereby  ratifying and confirming any bargain which he may make with any attorney for this purpose.

We the undersigned heirs at law of Aaron Booram deceased, agree to pay to Henry Snow, the different sums annexed to our names for professional services to be rendered by him in instituting and conducting a suit in the Court of Common Pleas of Hamilton County, Ohio, for the purpose of setting aside the last will of said Aaron Booram. Said sums of money  are to be paid by the subscribers individually upon the termination of the suit, provided it shall be decided in our favor. But if decided against us than we are to pay nothing for said services.
And the said Snow agrees to institute and conduct said suit to its termination for the different sums hereto subscribed, provided they amount in all to five hundred dollars. And if unsuccessful in said suit he agrees to charge nothing for his services.
