<<< Anyone you know have Spanish/Portuguese Jewish background? >>>

Many of us do, and once that is determined it seems that everyone who does have this ancestry can trace the relationship to each other, often just through one marriage, but usually through two and occasionally need three marriages to make a family connection. (Not based on a scientific or mathematical analysis - just my experience.)

With me it as follows:-

Maternal grandmother's mother's family - paternal family name from there is VIEYRA

Maternal grandmother's father's mother's family - paternal family name from there is JUDA RODRIGUES

They were primarily from Amsterdam, but possibly also from Hamburg. Most came and lived in London during the 19th century, but a few family members came earlier according to Bevis Marks records. This is a typical pattern in many families.
