I am trying yet again to find these brothers. Although born in 1862, 1868 and 1873, they are not be found in the 1880 census and Robert is not in the 1900 census. They were all born in NYC, mother's name Isabella Wilkie, father Steward May Curtis. They moved to Brooklyn in the 1870's. Isabella died and Steward remarried an Adel Thompson and had a son Alfred C. Curtis in 1877. Ring any bells? Linda
