John and Roseanna Smith Miles

John Miles, born in 1958 and Roseanna Smith, borm in 1848, lived in New York City in 1891 when their 6th child was born. They turned him over to the New York Foundling Hospital and when he was 5 years old, he was sent to Missouri to live with Luke Summers' family. We have the birth certificate for young Robert Miles (later Summers). We are searching for his brothers and/or sisters descendants.
