Vivian, I can answer a few of your questions -but have no direct information about your Julien family.The Catherine Savage who married Daniel Stewart was the daughter of George Penn Savage and Elizabeth Miller.The Savages came to Ohio from Nelson co VA.
Snow, Sarah, and Cynthia Richardson are all children of Zebediah and Phoebe (Charles) Richardson. Zebadiah was b 26 Jan 1768/69 in Amherst, Hampshire co MA.He died 15 Dec 1822 in Houston, Shelby co OH.Phoebe Charles was born 5 May 1740, Hudson, Hillsborough co NH.She died in 1822 in Fryeburg, Oxford co ME.They married c 1790 in Chatham, Carroll co, NH. The Richardsons also had a son named Zebediah.It must have been the son who signed the 1829 will since the father died in 1822.
Their daughter Mary "Polly" married first John Mangan/Mangin who served in the army at Ft Wayne.He was born in the Kingdom of Ireland.After his death (bef 18 Jan 1823), Mary married John McClure, Sr.John helped Mary settle her first husband's estate. I have some early information on the McClure family (a booklet).The McClures went to Allen Co IN - then moved on to DeKalb Co MO where they are both buried in the Hopewell Baptist Church cemetery.It looks like you have a good bit of info on the Stewart family.Seems that both the Richardson and Savage families are connected to them by marriage.I'm not sure how the Huston and Julien groups fit into the above picture - but I am surely interested.
