Hello Don. I'm wondering if my Great Great Grandfather George F. Pinkham, whom we don't know much about, is the same one you're talking about here. Ours was a blacksmith in Oakland in the 1870's where he lived at 23rd and Broadway. He is also apparently buried in Oakland. By second marriage to a McClenny (first name unknown) he had a daughter named Beulah Freema Pinkham (my Great Grandmother) born on September 10, 1876 in Oakland, whom we believe had two brothers named Ralph and Robert and at least one sister named Ethel.Does any of this jive with your records?
