I never knew an apprentice [he said] contented with the clothes allowed him by his master, let them be what they would. Jemmy Franklin, when with me, was always dissatisfied and grumbling. When I was last in Boston, his aunt bid him go to a shop and please himself, which the gentleman did, and bought a suit of clothes on my account dearer by one half than any I ever afforded myself, one suit excepted; which I don't mention by way of complaint of Jemmy, for he and I are good friends, but only to show you the nature of boys.

What a good friend he proved to Jemmy, when the latter became his own master, we have seen. The erratum of which Franklin was guilty in his relations to his brother James was fully corrected long before he left a will behind him conferring upon James' descendants the same measure of his remembrance as that conferred by him upon the descendants of his brother Samuel and his sisters.

Four of Franklin's brothers died young, and Josiah, his sea faring brother, perished at sea not long after he excited the dudgeon of his uncle Benjamin by his indifference to his uncle's line of thanksgiving.

As long as Franklin's brothers John and Peter were engaged, as their father had been, in the business of making soap and candles, Franklin assisted them by obtaining consignments of their wares from them, and advertising these wares in his newspaper, and selling them in his shop. Later, when he became Deputy Postmaster-General of the Colonies, he made John postmaster at Boston and Peter postmaster at Philadelphia. Referring to a visit that he paid to John at Newport, Franklin says in the Autobiography, "He received me very affectionately, for he always lov'd me." When John died in 1756 at the age of sixty-five, some years after his brother Benjamin had thoughtfully devised a special catheter for his use, the latter wrote to his sister Jane, "I condole with you on the loss of our dear brother. As our number grows less, let us love one another proportionably more." John's widow he made postmistress at Boston in her husband's place.

Peter Franklin died in 1766 in the seventy-fourth year of his age. As soon as the news of Peter's death reached Franklin in London, he wrote a most feeling letter to Peter's widow, Mary.

It has pleased God at length [he said] to take from us my only remaining Brother, and your affectionate Husband, with whom you have lived in uninterrupted Harmony and Love near half a Century.

Considering the many Dangers & Hardships his Way of Life led him into, and the Weakness of his Constitution, it is wonderful that he lasted so long. It was God's Goodness that spared him to us. Let us, instead of repining at what we have lost, be thankful for what we have enjoyed.

He then proceeds, in order to allay the widow's fears as to her future, to tell her that he proposes to set up a printing house for her adopted son to be carried on in partnership with her, and to further encourage this son if he managed well.[26]

Of Franklin's brother Samuel, we know but little.

Franklin's oldest sister, Elizabeth Dowse, the wife of Captain Dowse, lived to a very great age, and fell into a state of extreme poverty. When he was consulted by her relations in New England as to whether it was not best for her to give up the house in which she was living, and to sell her personal effects, he sent a reply full of wise kindness.
