I don't know if there is a connection to your Mickel, but here are some tangential references to the Mickels in the Gloucester, NJ area much earlier.Perhaps they are connected.
Hannah Ladd was a Mickel.Her husband, John Ladd, Jr., left to her the bulk of his estate, some 6,000 or 7,000 acres, with a few hundred acres going directly to his nephew, John Ladd Howell.In addition, by his will, some 1,600 acres were to pass to John Ladd Howell upon the death of his widow, Hannah Ladd. She gave her consent at one time to her nephew, John Ladd Howell, to clear the fisheries, since known as the Fancy Hill Fishery. Consequently he arose very early one morning to go to Phila. to make the necessary purchase of twine, etc., with which to construct his seines, when he met the old lady coming down from her bedroom. She told him she must revoke the permission, as she remembered a promise she had made to her kinswoman niece-in-law, Deborah West (daughter of Samuel Ladd), who owned the West Point Fishery, that no fishery should be established immediately below, as it might interfere and injure hers above. This was a most unjust and unwise pledge, as John Ladd Howell, the prospective owner of the contemplated fishery, and Deborah West stood in precisely the same relation to her deceased husband, the one being his brother's daughter, the other the son of his sister Katherine.The consequence was most unhappy -- John Ladd Howell was hurt and indignant and never spoke to his aunt afterwards, though living in part of the same house, "The Old Place". Some eight years after John Ladd Howell's death, about 1793, she was prevailed upon to yield a reluctant consent that his grandnephew, Joshua Ladd Howell should clear the fishery.This fishery proved to be for many years a lucrative one, and did not materially injure the one above, or West's Fishery.Joshua L. Howell purchased the West Point Fishery of Deborah West's descendants. Hannah Ladd (says Samuel Mickel), daughter of John and Hannah (Hopkins) Mickel, born May 27, 1715, died January 27, 1797 in her 82nd year. She made her will October 5, 1792, bequeathing to her niece, Frances Paschall Howell, widow of John Ladd Howell, $5,000; to her grandnephew, Joshua Ladd Howell, an oval dining table and eight silver spoons marked "J.E.L.", initials of John Ladd Sr. and Elizabeth, his wife; and to his wife, Anna Blackwood Howell, a bureau and looking glass. The rest of her estate, consisting of 6,000 or 7,000 acres, was divided among her relatives, the Mickels and Hopkins. The 1,600 acres, which by John Ladd, Jr.'s will became the property of John Ladd Howell, now deceased, descended to his son and heir, Joshua Ladd Howell. Her will was proved February 2, 1797 (See Liber 37 of Wills p.97 Sec. Of State's Office Trenton). Among the papers of the late Samuel Mickel, now  in the possession of Miss Martha Mickel, was the following "Pass" for Mistress Hannah Ladd, given her by the Hon. John Cooper who, at that time was a member of Council, the upper branch of the Colonial Legislature.He owned and built the house occupied by Miss Sarah Campbell and Mrs. Barton, daughters of the late Amos Campbell, Esq., at present owned by Dr. Clarence Abbott.This house was headquarters of Lord Cornwallis while here with six regiments of British troops, november 1777:
The bearer Mistress Hannah Ladd,
Neither very good, nor bad,
Aged as appears to me,
Not far short of thirty-three,
With stockings tied below the knee;
Of complexion rather fair
Flaxen colored is her hair;
Her stature neither great nor small,
Her eyes, perhaps you'd hazel call;
A traveler from here to there,
And may be let go anywhere;
Has permission with the mare,
Her horses and her carriage,
To travel all New Jersey o'er,
If well she pays her ferriage.

George Fox had enjoined upon his followers kindness toward the aborigines.It appears that Hannah Ladd obeyed this injunction, not only in its spirit but in letter, for Anna Blackwood relates that Indians often came to Hannah Ladd's, at the `Old Place,' and would make this demand for food `Hann Ladd more Souk!'(soup) and after partaking plentifully of this, they would turn their saucers upside down on her clean tablecloth and then say `Hann Ladd more meat!' She made no remonstrance against this aboriginal inelegance, but submitted with a true `Friendly spirit.'
