Michael Kritzer (b. 28 Sep 1805), son of Sebastian Kritzer and Rosina Tritshler, married Maria Agatha Hall (b. 29 Mar 1822), daughter of Johann Hall and Brigitta Engesser, at St. Johann, Donaueschingen, on 26 Apr 1841.

Michael and Agatha (as she appears to have been known) had five children, all also baptised at Donaueschingen's Catholic church of St. Johann.

1. Rosina Kritzer b. 12 Mar 1842, bap. 14 Apr 1842 
2. Wilhelm Kritzer b. 10 Jan 1844, bap 14 Jan 1844
3. Wilhelmina Kritzer b. 8 May 1845, bap. 18 May 1845
4. Anna Kritzer b. 6 Jun 1849, bap. 10 Jun 1849
5. Augusta Brigitta Kritzer b. 19 Aug 1858, bap. 29 Aug 1858

Michael Kritzer died, aged 61, in Donaueschingen on 1 Apr 1867.

Anna Kritzer and three of the children of Wilhelm Kritzer came to England. 

Rosina Kritzer married Josef Johann Baptist Seemann, in Donaueschingen, on 30 Sep 1869 and Wilhelmina Kritzer married Carl Emil Boll, again in Donaueschingen, on 29 May 1873. This last couple had at least seven children, giving the potential for further family still remaining in the area. There are no further records showing up for Augusta Brigitte Kritzer. There's evidence of this family, in this parish, right back to the 16th Century.

The German surname Kritzer, it is said, is derived from the Old German word "Kretscham," meaning "inn." The name was most likely first borne by an innkeeper. An alternative suggestion is as a South German occupational name for a coiner, from krüzer Kreutzer.  

William Ball and Sarah Jane Tubb

William Ball (b. 1806), Bachelor, married Sarah Jane Tubb (b. 1812), daughter of William Tubb and Sarah Chard, at St Mary's Church, Portsea on 24 Apr 1832. Witnesses were Mary Ann Ball and William John Long.

William and Sarah Jane Ball had one daughter:

1. Sarah Louisa Ball bap. 29 Sep 1833 at St Mary's, daughter of William Ball, Seaman and Sarah of Lake Lane, Portsea.

The next time we find them is in 1851, when William Ball (45) Shipwright Greenwich Pensioner from Portsea, Hampshire; Sarah Ball (39) and Sarah Louisa Coombs (18) were living in Church Path, Portsea.

Sarah Louisa Ball (18) of Church Road, Portsea, daughter of William Ball, Carpenter, had married William Coombes (26) Seaman, HMS Illustrious, listed as son of John Coombs, Shipwright, also at St Mary's Church, Portsea on 11 Jan 1850. Witnesses to their marriage were Mary Ann Horner and William Ball. William and Sarah Louisa Coombes appear to have two children: William Coombs b. 1852 M Quarter in PORTSEA ISLAND UNION Volume 02B Page 415 and Louisa Coombs b. 1853 D Quarter in PORTSEA ISLAND UNION Volume 02B Page 359. I can find no further records for any of them.

William Ball, we must assume, died between 1851 and 1853.

In 1853-54 Sarah Jane Ball appears to receive payment related to Greenwich Hospital out-pensioners - a final pension payment perhaps?

On 24 Apr 1853, again at St Mary's Church, Portsea, Sarah Jane Ball, Widow, daughter of William Tubb, Ropemaker, married Joseph Leach, Blacksmith, Widower of Havant Street, listed as son of John Leach, Farmer. Witnesses were Mary Windel and Henry Tubb, Sarah Jane's sister and brother.

[So far] I've yet to find any further records for any of them.
