I'm looking for background on Sarah Anne Boulstridge. She married Koscuiska (also spelt as Kosciusko and Koscinska) McDonald (from Bedfordshire England)in November 1830 in Coventry, Warwick, England. They had a son named James Kosciusko McDonald who was christened Sept 1840 in Liverpool, Lancashire, England. They then moved to Australia circa 1840/1841. In total they had 7 children, but only 2 boys (Kosciusko and Donald) and 1 girl (Sarah Elizabeth)survived to adulthood. Any assistance would be greatly appreciated.
