ROGERS, Attorney, &c to William H. Seward, May 13, 1867

Mr. Rogers to Mr. Seward.

Sir: I beg leave to refer you to my letter of 29th April, ultimo, and to the response of Mr. F. W. Seward, Assistant Secretary, of 5th May, instant, in relation to the case of William Jackson, otherwise called John McCafferty, now imprisoned, and, as would appear by Atlantic cable telegrams of last week, tried and convicted of high treason, in Dublin, Ireland.

I have waited since the reception of the last-named letter, in order that I might hear from Sandusky city, Ohio, where the parents of McCafferty reside, and where he was born, before sending the affidavits (original) which I herewith transmit to you, duly verified before the proper officers, and certified by the clerk of the supreme court of this State. The proofs of birth and citizenship I expect within a few days, unless my letters to Sandusky city have miscarried, or unless those proofs have been transmitted to your department directly.

I would request, inasmuch as parties have been sentenced to be executed in Dublin within twelve days from this date, that copies of these affidavits be forwarded to our minister at London, and to our consul at Dublin, that they may be used either in obtaining a modification of the sentence, a new trial, or in any other proceeding you may deem proper in the premises.

I have the honor to be, very respectfully, your obedient servant,
