History gives us antecedents and a place in time.

John Brock, was born on the 24th of January, 1729. He married Elizabeth de Lisle, daughter of the bailiff of Guernsey and the couple had fourteen children, four girls and ten boys. John, a mid-shipman died at Dinan, France at the age of forty-eight. In chronological order their children were:

1. Elizabeth born in 1756 died in youth.

2. Rebecca born in 1758 died in youth.

3.--------------------------- John-------------------------------

was born in 1759. He joined the 8th Regiment of Foot (King's) as an ensign. Later he became a brevet lieutenant-colonel in the 81st Regiment. He was killed in a duel at Capetown, South Africa in 1801. 

4. Ferdinand was born in 1760. He served in the 60th Regiment of Foot, the famous Royal American Regiment, which was raised in the colonies at the time of the conflict with France and served with distinction during the American Revolution. Ferdinand was killed by a Spaniard at age nineteen at the defence of Baton Rouge on the Mississippi River.

5. Peter Henry was born in 1761 and died an infant.

6. Daniel De Lisle was born on December 10th, 1762. In 1795 he was elected a jurat [* See Below] of the royal court. He went to London in connection with trade and other ancient privileges of the island. Afterwards he assumed the very influential position of lieutenant-bailiff or chief magistrate of Guernsey. He was responsible for building Elizabeth College which today is a very popular boys' school.

7. William was born in 1764. He was a merchant banker in London and with his brother, Irving, was engaged in trade with Russia, Sweden and Prussia on the Baltic Sea. William took a keen interest in Isaac's career and gave him money to purchase his various commissions. William intended the money as gifts, but unknown to William the cost of each purchase was entered on the company's financial records as loans. Some eight hundred ships insured for 40% of their value suffered various misadventures in the Baltic Sea including being lost at sea, taken by privateers and seized when they arrived in port. Napoleon said "England is a nation of shopkeepers," and he set up a blockade of Europe to prevent Britain from trading with European countries. Some of the above-mentioned shipping disasters resulted from Napoleon's blockade. In 1811 because of its various shipping misfortunes, William's company suffered a financial collapse and went into receivership which resulted in all outstanding loans being called in including the amounts William used to purchase Isaac's commissions. This demand for repayment of money they did not have plunged the Brock family into serious financial straits.

8. Peter was born in 1765 and died young with no issue.

9. Elizabeth was born in 1767. She married John Elisha Tupper of Guernsey, and they had three sons and one daughter: (a) one of the sons, Ferdinand Brock Tupper, wrote The Life and Career of Major-General Isaac Brock in 1847. Ferdinand had no children.

(b) Henry Bingham Tupper inherited the portrait of Isaac Brock from his Uncle Irving. Henry married and had a son who also married and had a son who died while young.

(c) Henry Tupper was born in 1809. He married and had one daughter Henrietta Tupper.

10. Frederick born in 1768 married a Miss Levat. They had no children.

11. Isaac born October 6th, 1769; died October 13th, 1812.
