Further strengthening my theory that Grinbergs and Akerfelds (outlined HERE) were used by the same people as alternative surnames is the trail left by Lotte Grinbergs and her son Jekabs.
In 1896 at Embute church, an unmarried mother living at Sudmalkalns farm in Lieldzelda estate named Lotte Grinbergs baptised a daughter named Annlise Grinbergs. Annlise’s godparents were Kristaps Akerfelds, and Annlise Grinbergs, wife of Ernests Akerfelds. Lotte next had a son at Sudmalkalns farm, named Ernests in 1902, baptised at Embute (unrelated godparents).
An unwed Lotte Grinbergs also shows up in 1906 at Rudbarzi estate, baptising a son named Jekabs at Skrundas church. Jekabs’ godparents are Ilze Grinbergs and Ieva Grinfelds (is Grinfelds an amalgamation of Akerfelds and Grinbergs?).
Normally this wouldn’t be enough for me to solidify a relationship between Lotte Grinbergs and anyone named Akerfelds. But I’ve had the luck of a)talking to Jekabs’ daughter and b)getting a glimpse at the 1935 census of Rudbarzi.
Jekabs went by Akerfelds, not Grinbergs. As does his daughter, living in Latvia to this day!
This sure does complicate things. Did all Grinbergs also go by Akerfelds? Surely not, its a very common surname. Did all Akerfelds go by Grinbergs at some point? My own great-great grandfather Jekabs (same generation as Lotte – siblings?) did. It seems that they tended to use Grinbergs more for girls and Akerfelds for boys. In my great-great grandfather Jekab’s daughter Anna’s baptismal record, they used Grinbergs, not Akerfelds or Akerfelds alias Grinbergs like they did for their sons, for example.
