My Briggs Line

I am in hopes someone can help me with my research. I made some mistakes and had to remove what,I thought was my line.
I start with my Grandmother: Catherine Minerva(Briggs)Harrison B: May 13,1919 Stillwater,Washington, MinnesotaD:Winter Haven,Polk,FL.
Her Father was Van Berg/Berge(V.B.)Briggs B: April 8,1889 Hannibal ,Marion,MOD:Oct 22,1962 Lovelock,Pershing,Nevada. V.B had two Sisters Amelia BriggsB: 1890 Mo D:? MIA after 1920.Another Sister Avis Briggs B: 1892 ILLD:? MIA after 1920. Their Father was Ira Horton BriggsB:1862NYD:1934MO. I thought that Ira's father was Luther, but I was wrong but they may be related. Ira's Father was Erastus Chamberlain (E.C.) Briggs B:1833 D: ?. Does anyone else have this line?Thank you for your help.
