Newfoundland's Grand Banks Message Board

I am trying to find information on the famiy of John Joseph Evans of #34 Prescott St., St. Johns.

Born 1861 - Died 1944. He was the owner and publisher of 'The Newfoundland Quarterly' from 1901-1942. His wife was Agnes Stephenson. There children (all born in St. Johns) were:
John Joseph Evans Jr. born Nov. 15, 1888
William Patrick Evans born Oct. 11, 1890
Helena Evans born July 30, 1892 (Twin)
Mary Evans born July 30, 1892 (Twin)
Agnes Evans born Oct. 1894

I am particularly interested in John Joseph Jr. (who took over the publication of 'The Newfoundland Quarterly' from 1842-1951. I do not know the name of his wife but his children (all born in St. Johns) were:
Elizabeth Evans
Agnes Evans
Dorothy Evans
I believe there were two other children (Mary & Catherine)

Hoping others are also researching this particular Evans Family.

Thank you
