Henry Alexander Anderson b.1835 Weymouth, Dorset, England

Does anyone else have a connection to the Weymouth Andersons? I think Henry's parents were Peter Anderson born in Scotland about 1806 and Maria ? 1811 from Weymouth. Peter was a mason and Maria a dressmaker with her own shop.
Henry was a mariner and had 8 brothers and sisters (I think) James (1834), John (1840), Agnes Maria (1841)John William (1843), James P (1845), Charles F(1847), Mary A (1852), Charles R (1853). It's more than likely that I've got the brothers and sister's wrong as they are based on the census info an some times they put grandchildren down as children or spell the names differently, so I've just written them down to give an idea, hopefully someone out there is also a common descendent of Peter and Maria.
