It is well with my soul.... written by Horace Spafford.
From Wikipedia:This hymn was written after several traumatic events in Spafford’s life.
The first was the death of his only son in 1871 at the age of four,
shortly followed by the great Chicago Fire which ruined him financially (he had been a successful lawyer
and had invested significantly in property in the area of Chicago which
was decimated by the great fire). His business interests were further
hit by the economic downturn of 1873 at which time he had planned to
travel to Europe with his family on the SS Ville du Havre.
In a late change of plan, he sent the family ahead while he was delayed
on business concerning zoning problems following the Great Chicago
Fire. While crossing the Atlantic, the ship sank rapidly after a collision with a sea vessel, the Loch Earn,
and all four of Spafford's daughters died. His wife Anna survived and
sent him the now famous telegram, "Saved alone . . .". Shortly
afterwards, as Spafford traveled to meet his grieving wife, he was
inspired to write these words as his ship passed near where his
daughters had died.
He did later have more children, one of which died in infancy. He and his wife and the two children moved to Israel
