My two great-great aunts died on the same day, 4th January 1842.
The Cambrian of 22nd January 1842 reported the funeral:
In a former paper we mentioned the deaths, within hours of each other, at the respective ages of 20 and 17 years, of Emma and Sarah Evans, the eldest daughters of John Evans Esq., foreman manager of the Dowlais Iron Company. They were consigned to the "house appointed for all living" on Saturday the 8th instant, amidst the sympathy of a very numerous and highly respectable assemblage on that mournful occasion. It was, indeed, a scene of deep sorrow. The extreme affliction of the worthy mother, almost sank, also to the grave by long days and nights of intense watching around the beds of sickness and of death; and the anguish-wrung ejaculation Oh! My daughters! of the grieved father, over the grave as they were laid, side by side, in their last earthly abode, excited unusual sympathy. "I shall go to him, but he shall not return to me," said the chastened King of Israel, when at the death of his son, he dried his, then, unavailing tears and sought consolation. The operations of the works were suspended, in respectful regard, during the funeral.
