I am not researching these people, just entering information from the book "Pioneers of Old Monocacy" by Tracey & Dern:
"Captain Robert Debutts is said to have been a brother of the Rev. Lawrence Debutts of Maryland's Established Church.The latter was licensed to Virginia in 1721 but came to St. Mary's County in Maryland in 1734. (In another chapter a Lawrence Debutts was mentioned in St. Mary's Co. about 1750.) Seemingly Robert Debutts was in possession of 'Albin's Choice' on March 23, 1746/47 when he wrote: 'Whereas in all appearances my wife Anna Debutts is now in a very sick and languished condition and is likely to leave behind my son John Donaldson Debutts, her only child, not three weeks old..to manifest my tender affections to her and her dear child, I hereby voluntarily and freely give unto my said son my dwelling plantation called 'Albin's Choice' containing 300 acres of land with all improvements and everything given and delivered unto his mother, my wife, by his grandfather John Donaldson, after my decease.'Subsequently, on October 23, 1751, Debutts mortgaged 'Albin's Choice' to Daniel Dulany for 176 pounds, and then conveyed it and 264 acres of 'Spring Garden' to Dulany three days later for 375 pounds." (This land might have been in the area of what is now the Frederick airport.)
"Elsewhere Robert Debutts had other land holdings.In 1752 'Sun is Down and Moon Is Up' was surveyed for him in the Middletown Valley.Much earlier still, on March 25, 1742, he had had 'Debutts Hunting Ground' surveyed.It was located near today's village of Middlepoint, northeast of Myersville, and was the first survey in that western area.In 1758 Luke Barnard, stepson of Nathaniel Wickham and son-in-law of Debutts, assigned the Middlepoint property to Johnb Ferguson, in turn the second husband of Debutts' widow Abigail."
"Robert Debutts on April 24, 1749 appointed his 'loving friend' Peter Butler as his 'true and lawful attorney' to aid him in the collection of debts.But there is no mention of Butler in Debutts' will, drawn up three years later.The will names as daughters Mary-Ann-Christian-Abigal Debutts (sic) and Margaret Barnard, the wife of Luke Barnard.It provided for the division of his land between his son John Donaldson Debutts and the 'child with which my wife in now big.'This second wife, Abigail, who later married John Ferguson, was named as executrix."
There are quite a few listings in the index for Robert Debutts.There was no other listing for John Donaldson, father of Robert's first wife.
