He rose, by slow degrees, from being the poorest, to be the richest man in Ireland. He commenced business as an itinerant bookseller at Belfast ... The knowledge he thus acquired of public sales, procured him the situation of clerk to an auctioneer in Dublin. There he opened a small book-shop, became eminent in that line, sold lottery tickets, and by his speculations in the funds, and contracting for government loans, acquired his enormous wealth.
White subscribed £3,000 to the anti-Union campaign in January 1800 and in April the Irish government contracted with him for a loan of £1,500,000, whereupon a Castle official commented that White ‘notwithstanding his politics, would not have bid so high if he thought the Union would not be carried’. A first instalment of £75,000 as security on the loan was paid, but the second of £225,000 was not and White stood to forfeit the first. His petition to the Irish parliament alleging that a leak had depressed the funds on which he depended was supported by Isaac Corry, 15 July. It was not a severe setback for White who bought Lord Carhampton’s estate for £96,000 and was later reported to have spent some £200,000 on his attempts to get himself and his sons into Parliament.
In July 1805 White informed the Castle that he meant to stand for county Dublin and hoped for their support. He was admitted to be ‘a very proper person’, though no promise was given him then, nor in November, when he applied again.
White was counted in opposition during his first Parliament.
