My grandfather John M. Costs arrived here in Boston in 1884. He traveled to California where he met and married Adeline Rogers/Gonsalves.(Some of Adelines family used Rogers and some stayed with Gonsalves).They had 3 children, Albert, Helen and Florenced.John died in Hayward, Ca. in 1936 and Adeline in Fremont, Ca. in 1965. I have found no siblings for John but Adeline had 24 brothers and sisters: Mary Rogers/Gonsalves/Nunes Rose Rogers/Gonsalves/Cardoza Minnia Rogers/Gonsalves/Moitoza Annie Rogers/Gonsalves/Ashadino Helen Rogers/Gonsalves/Lesh Elsie Rogers/Gonsalves /Bewall Joseph Gonsalves/Rogers Albert (Bert) Gonsalves/Rogers Bill Gonsalves/Rogers Jack Gonsalves/Rogers Manuel Gonsalves/Rogers Emma Rogers/Gonsalves/Martin Henry Rogers/Gonsalves Katherine Gonsalves Isabel Rogers/Gonsalves/Frances Frank Gonsalves/Rogers
The above siblings were all I have found, the others may have died at birth or in early childhood.The obit for Adelines father Manuel Gonsalves read "Father of 24 Dies in Hayward".
Anyone having any information please get in touch with me.
