Hi Lucy,
I don't think there is any connection, although the names and dates are very interesting to me. Our family immigrated from Lebanon in the late 1800's (probably 1898). My research has inticated our name is of Lebanese origin. My Great Grandfather was from Basloquit, Lebanon. Although he refered to it as Ol' Syria.
I have found some Butrus families in Sydney, Australia. Our family initially lived in the Philadelphia area, and now both branches reside in N.J.
I will save the names and dates you have written and will let this message board know if I find any connection that might be of interest to you.
Best Regards,
George
