Karen:
In my SloughHouse Cemetery Book by Norma Baldwin RICKETS, there are two listings of BERGALA: Andrew and Rose. The book does not give dates but they are:
Andrew = b) 7-28-1872 ~ d) 1-16-1942 in Amador Co. @69y
Rose = b) 5-27-1886 ~ d) 1-15-1951 in Amador Co. @ 64y.

Rose is listed as a sister to Louisa (BEAVER) PUTT, wife of Joe PUTT: both also buried in SloughHouse Cemetery, Sacramento County. The death records for Rose show that her parents are Mother (?) DECK and Father (?) EDWARDS. I do not know where the information came from on the death record. Perhaps you can obtain that document from Amador County.

If you do not already have this:
J.F. BOWSER married 1-1-1894 Book D Page 395 ElDorado Co CA to Mary BERGALA.

Nora Bernice BERGALA: b) 11-20-1912 - Sacramento
d) 3-4-1943 - Placer Co. @30y.

Francisco BERGALA had land in El Dorado County: 10-20-1890.

Frank J. BERGALA: b) 8-7-1875 d) 7-1-1972 in Sacramento Co. (m)12-9-1904 Book E pg 317 to Eva HART in El Dorado Co. CA

I also have a few other BERGALA names if you are interested.
I hope this helps you:
