I also have the D'ORAZIO's and the DiGUGLIELMO's on my family tree.I have a strong feeling that we can all connect the dots for each other.Here goes on who I have.On the D'ORAZIO side I don't have much but this is it:
My gggrandfather's name is Domicantonio MASCIANTONIO married to Maria D'ORAZIO they were married in the town Civitella Messer Raimondo Italy, their son was my ggrandfather Giocchino MASCIANTONIO who married Carmella DeMEDIO on March 9 1893 in Civitella Messer Raimondo Italy.Giocchino was born on March 4 1870.
Now the DiGUGLIELMO side I have quite a few.Starting with my gggrandfather DiGUGLIELMO Emidio born August 6 1847 in Civitella Messer Raimondo Italy Parents were DiGUGLIELMO Giuseppe and GATTONE Domenica don't know when they were born. But my guess Italy of the same town.
Emidio married MASCIANTONIO Maria Fedele.Her parents were MASCIANTONIO Angelantonio (father ?) MASTRIPPOLITO Antonio (mother ?) Emidio and Maria had 6 children:
Michele (son) born April 16 1876 parents were DiGUGLIELMO Emidio and MASCIANTONIO Giovina (mother) she must of died and Emidio remarried to Maria Fedele MASCIANTONIO who is the mother of the next children listed.
Domenica Givina (daughter) born September 2 1877
Antonio (son) (my ggrandfather) born January 31 1881 married Maria Angela DiMARTINO her parents were DiMARTINO Giovanni and MASTRIPPOLITO Eusebia
Palma (daughter) born March 17 1883
Maria Nicola (daughter) born July 5 1885
Filomena (daughter) born June 23 1887
Antonio DiGUGLIELMO and Maria Angela DiMARTINO had a son born on September 27 1901. His name is Emidio Alfredo DiGUGLIELMO and he was my grandfather.
Antonio - Palma - Maria Nicola - Filomena - Maria Angela and Emidio Alfredo all came over to the USA though Ellis Island and lived in Conshohocken PA.
Domenica migrated to France.
Now Emidio Alfredo DiGUGLIELMO married MASCIANTONIO Mary and these are my grandparents.
To my knowledge the D'ORAZIO's-MASCAINTONIO's-DiGUGLIELMO's-DeMEDIO's-DiMARTINO'S are all related in marriage some how.So I know somewhere in your line these people all fit.You may have gone back one or two more generations or another branch like their brothers or sisters.I hope we can connect and add to each of our families... :)
