Thank you for more search possibilities. There was a different informant on each death certificate. My mother, who was 24 when her mother died in 1938, was the informant for Anna Macikas. I assume my mother was told the Macikas name from either her mother or her dad, who was still alive and in his 50's at the time of Anna's death. My mother had no birth certificate, since it had been destroyed in a fire where the city records were kept. I have her baptism certificate which shows her mother's name as "Maciukas".
The informant for Anna's brother, John Macikas, was his son Anthony, who was 27 when his dad died in 1923. Grandma Anna is buried in St Casimir's Cemetery under her married name Ona Zakarienne with my Grandpa Alexander Zakaras and my uncles. I found John Macikas's plot this fall just a few rows from my grandparents, when I found John's death certificate, which had his burial info. The large name on the monument is "Macikai". And John's name is there as Jonas Macikas. I have not been able to find any censuses or anything else for John. Nor have I been able to find a census for Anthony. I did find Anthony's draft registration and his naturalization card, which had my grandfather listed as witness.
Both Anna's and John's death certificates list their parent's coming from Kaltineneu.
My mother had left a rough outline of her mother and father's family, although she did not list too much info. She showed her mother Anna having a brother John, who died in 1923 and he had a son Anthony and a daughter Josephine. Josephine's daughter is buried in the Jonas Macikas plot. The outline showed Anna had a sister Martha, who died in Europe and had daughters Violet and Sophie or Violet had a daughter Sophie. And there was another brother, Joseph, with the notation "single" "1930's".
My grandfather Alexander lived with us for a few years until his death in 1957, when I was entering high school. He did not speak English and I did not speak Lithuanian. So communication between us was very little, just gestures. My grandfather and mother had apparently lost touch with Grandma Anna's relatives, because they never visited us nor did we visit them.
Sad to think of it now. What a loss!
