ENDEDQUESTMother Sought 15 Yearsi6Her Childrenin VainDETROIT. Mich., Aug. 3.—Through the death of Mrs. John Pearson, a widow, in Boston, Mass., Mrs. Mabel Case, wife of Homer Case, leading banker of Rochester. Mich., and Wendell Von Wagner, prominent business man of Oxford, Mich., have received their first knowledge of the unknown mother for whom they have sought unceasingly since childhood.With Mrs. Pearson’s death ended the fruitless search that she had prosecuted for 15 years for her children.John Pearson, a sailor, was killed by a falling spar at Boston 30 years ago. The widow, left penniless with four children, placed them In the Baldwin Place Home for 30 days. At the end of that time she could take out only two. and the otherswere sent to Michigan with a carload of waifs and found homes in Oxford.Later, when fortune had smiled again upon the widow, she called for her children. only to learn that she had lostthem forever.The rules of the asylum prevented her from being told where they had been sent or by whom adopted. The other two children died and the distracted mother gave up her life to the quest for hermissing hoy and girl.She traced the car as far as Michigan and appealed to the Detroit authorities,but could find no clue.In the meantime the children had found excellent homes, been thoroughly educated and their own effort to settle theirreal identity was futile.Mabel, the elder, was married four years ago to Banker Case. She had been known as Mabel Knapp, taking the name of her foster-parents. In the same way the boy became Wendell Van W agoner.When Mrs. Pearson was found dead, kneeling by her bedside in an attitude ot prayer, the orphan asylum had no longer any reason for silence, and the children were communicated with.
