Beddome had at least seven siblings, as shown here.
John is the oldest and Benjamin is the next eldest and the longest lived with Joseph next after him. Next come Rachel, Mary and Bernard. These were all born in Henley-in -Arden. Then after a little gap Sarah and Martha (known as Patty) were born in Bristol. John died in childhood, only 12, and Bernard and Rachel were only 17 and 20 when they died in 1738, perhaps from the same disease. Sarah, who never married, was dead by the time she was 30. The other two sisters married but died relatively young (Martha was 39 and Mary 43). (Some authorities also list a Caleb born in 1729). Mary married Edward Bright (1740) and later Moses Brain 1726-1796 (1753). Through Moses she became the mother of Mary (1744-1819) and the short lived Rachel. Perhaps Mary died giving birth to Rachel or shortly after. Martha was married to Christopher Ludlow (1731-1789). Their children were Christopher Brandon and Martha.
