SEEKING JOHNSON & KEITH Lineages

I believe that these are my great great grandparents, by way of
son George F Johnson who married Lydia Louise SWETT by way of son George Albert Johnson who married Matilda "Tillie" Bushman. George disappeared about 4/15/1917, perhaps into WWI[?]
Tillie was granted a divorce in 1933, Boston, MA;
by way of their
Son Woodrow Johnson b 12/21/1916 Boston - d 7/14/2006 Newton, Middlesex co, MA.

Woodrow Johnson married (1)Eleanor May Davis 10/13/1940 in Newton where I was born 12/9/1942. They divorced when Woody returned from WWII in 1947. Both remarried to others.

I am seeking details of the families of
George Albert Johnson,
George F Johnson,
John F Johnson Sr who married 9/29/1861 Harriet Keith b abt 1846 NH - 6/6/1901 plus her lineage. She married (2) William Simpson, (3) Jacob Bean
