I am looking for any information about three siblings that emigrated from Bulgaria to America. The eldest, Theodore Theodoroff was born around 1888 in Orchanie and left through Hamburg in 1902. Grace Theodoroff (born 1890) and Benjamin Theodoroff (born 1892) lived in Sofia and arrived in America in 1907. These are the names that they had when the came to America. Are there variations of "Benjamin" or "Grace" that I should be using to search?
I believe their father could have also been called Theodore.
