p. 28in a discussion of kinship links:"These kinsmen by marriage occasionally proved to be more of a liability than an asset.Black George Macartney's son Isaac married the daughter of William Haltridge, a wealthy Dromore merchant, and was gradually drawn into the financial affairs of her brother, which eventually ruined him.This however is an extreme case, and is not representative because Macartney's brother-in-law was a landowner not a merchant..."
(didn't get the page no. for this)footnote regarding Isaac Macartney's land acquisitions:"Macartney later acquired property in Counties Down and Armagh which had been bought by his father-in-law, William Haltridge of Dromore."
p. 167-68"The high social standing of Ulster merchants such as Lennox must have helped them to be firm in their dealings with the gentry.(Isaac) Macartney himself was tenacious in pursuing debts owed by such gentry as the Chichesters and Uptons, assuring his Dublin correspondents that they would not escape "true dunning', but had difficulty in dealing with his own brother-in-law, John Haltridge, and avoided presenting bills to him whenever possible, explaining that a stranger was more likely to get money from him than a relation.However, Macartney's inability to take a firm line with Haltridge stemmed not from any difference in social status but from thei relationship, and this eventually let to his becoming responsible for Haltridge's debts which contributed largely to his own eventual downfall in the 1730s.Haltridge had inherited a considerable fortune and property from his father, the merchant William Haltridge of Dromore, but had unfortunately failed to inherit any of the latter's financial acumen.Although his difficulties were in part caused by a ruinous lawsuit to recover his wife's dowry, Haltridge's main problem was one which he shared with most of those described as bad payers by the merchants, namely an inability to live within his income, leading inevitably to a slide into debt."
