There is a chapter written and researched by Edith Loughborough Mulford titled: John Loofbourrow of Woodbridge, Founder of the Loofbourrow Family in America.
I'm unable to copy the text, but it is noted in this chapter that the connection of John back to Britain has been unsuccessful. However the NJ Archives has a list of passengers on the Thomas and Benjamin that sailed from Scotland in Nov 1684 and landed at Perth Amboy in Feb 1685 with a John Loofbourrow listed as "miller, free passenger". We know that John was a Quaker and came to Perth Amboy, NJ in Feb 1685 and had settled in Woodbridge, NJ on Oct 7, 1686. He was active in the Amboy Monthly Meeting and it was announced in Sep 9 1687 that he would marry Gertrude Holland. However, she died before they married. He subsequently married Hannah Bunn in Nov 22, 1688 before Samuel Hale, Justice.
He acquired a great deal of land in and around Woodbridge where he had a mill.

Milton R. Lufburrow's research as of 1953, states that, "John Loofbourrow II and his seed produced the most prolific crop of Loofbourrow's of whom I have any record. ... almost without exception, they spell their names as it was originally spelled by the immigrant, John I, - LOOFBOURROW. It sometimes has a variance to Loofboro. Before his descendants arrived in Ohio about the year of 1800, in Lafette County, Pennsylvania and Bradford County, Pennsylvania, it was sometimes called Loveberry by one branch of his descendants."

Milton R. Lufburrow also claims that John II descendants are the only ones in the Loofbourrow family that he has found, who can claim relationship to Royalty:

"WADE FAMILY LINE, THE ROYAL BRANCH"

"David I, King of Scotland; Prince Henry, Earl of Huntington; David; Margaret; Helen McDonal; Helen DeQuincey; Eudo DeZouche; Ellen DeZouche; William Harcourt; Thomas Harcourt; Richard Harcourt; Alice Harcourt; Elizabeth Bessiles; Anne Pettiplace; Mary Purefoy Md; Thomas Thorne ‏(line to this point reported to be taken from 'Our Family Tree' by David Starr Jordan)‏; Susannah Thorne Md. Capt Roger Dudley; Thomas Dudley b 1576, Northampton, Eng. d July 31, 1653, ‏(1673?)‏, Gov. Mass. Bay Colony Md. Dorothy York; Anne Dudley b 1612, the noted Poetess, England d Sept. 16, 1672 Md. Simon Bradstreet Gov. of Mass. Bay Colony; Mercy Bradstreet b 1646, d Oct. 6 1714 Md. Major Nathaniel, son of Johnathan Wade, earlier settler of Mass.; Nathaniel Wade ‏(Rev)‏, b July 13, 1675 Woodbridge N.J. Md. Mary Davenport; Abigail Wade Md. John Loofbourrow II."

Another account states, Abigail Wade's ancestors were:
"Governor Bradstreet was born in England, 1603. Came to America in 1630 with Governor Winthrop and settled in Andover, first section of the Colony of Massachusetts Bay, 1630-1636. He was governor from 1672-1675. He first married Ann Dudley who was the first poetess of note in New England. One of her brothers was later Governor of the Colonies. She died Sept. 16, 1672."
